Physics 1025FGeometric Optics OPTICS Dr. Steve Peterson [email protected] 23: Geometric Optics In this section, we will use the ray model of light to understand the formation of images by mirrors and lenses through the processes of reflection and refraction.The Ray Model of Light Light rays appear to travel in straight lines. This assumption is the basis of geometric optics. The straight line paths that the light follows are called light "rays". A light ray is a line in the direction of the flow of radiant energy.Light: An Electromagnetic Wave In actual fact, light is an electromagnetic wave, as are radio, UV, infrared, gamma and micro-waves. An electromagnetic wave is composed of electricand magnetic waves which are perpendicular to each other, and to the direction of propagation.Electromagnetic Spectrum Electromagnetic waves can have any wavelength; there are different names given to different parts of the spectrum. The human eye only responds to EM waves in the wavelength range 400 - 700 nm, and we refer to these electromagnetic waves as "light".Light: An Electromagnetic Wave This is the speed of all electromagnetic waves (including light) in free space (vacuum). In gases, transparent liquids and solids light travels more slowly. Maxwell calculated the speed of propagation of electromagnetic waves, he found:Index of Refraction The index of refraction of a medium is the ratio of the speed of light in vacuum(c) to the speed of light in the medium (v): The index of refraction is never less than 1, and values for various materials are given in Table 23-1.Reflection and Refraction When light encounters a boundary between two media the radiant energy can be: (i) reflected (ii) transmitted (iii) absorbedLaws of Reflection and Refraction • The incident, reflected and transmitted rays all reside in the same plane (the “plane of incidence”) which is normal to Presentation on theme: "Geometric Optics."— Presentation transcript: 1 Geometric Optics 2 Outline Basics Reflection Mirrors Plane mirrors Spherical mirrorsConcave mirrors Convex mirrors Refraction Lenses Concave lenses Convex lenses 3 A ray of light is an extremely narrow beam of light. 4 All visible objects emit or reflect light rays in all directions. 5 Our eyes detect light rays. 6 We think we see objects.

When light is reflected off a mirror, it hits the mirror at the same angle (θi, the incidence angle) as it reflects off the mirror (θr, the reflection angle). The normal is an imaginary line which lies at right angles to the mirror where the ray hits it. 11 Mirrors reflect light rays. 12 How do we see images in mirrors? 13 How do we see images in mirrors?object image Light from the object reflects off the mirror and converges to form an image. 14 Sight Lines object imageWe perceive all light rays as if they come straight from an object.

GEOMETRICAL OPTICS AND THE GEOMETRICAL

Background Geometric optics explains how optical devices (such as lenses and mirrors) create images by considering that light travels in rays, which are straight lines emanating from a light source or reflected from an object. A ray diagram is a useful tool in geometric optics; it describes images formed by lenses or mirrors. A ray diagram can help: Figure 1. The Human Eye In the design of optical devices such as microscopes, telescopes, or movie projectorsExplain how the human eye creates an image formed on the retina, which our brains interpret for us as sightDetermine how to correct our sight when an abnormality in our eyes blurs our vision Figure 2. Ray diagram for a converging lens. Consider the ray diagram in Fig. 2, which is for a double convex lens. The left arrow represents an object such as a building or a tree. A few simple rules describe how rays of light refract when they pass through a thin lens like the one in this diagram or the ones in our eyes. Rays traveling parallel to the center axis (perpendicular to the center of the lens) refract so that they pass through the focal point on the other side of the lens. The place where the rays converge shows where the top of the arrow would be in the image formed by the lens. Different lenses and mirrors require slightly different rules when you draw their ray diagrams, but the ray diagram in Fig. 2 is similar to how the eye makes an image. Figure 3. Ray diagram for the human eye. Fig. 3shows a ray diagram that describes the image formed on the retina of a human eye. The eye, using tissue instead of glass, works like any other optical device such as a telescope or a camera.. Download Geometrical Optics PDF. Found 73 PDF Ebooks .

Lens model and the name of the original file.To delete the DxO Optics Module, click on the trash icon, in the upper left corner of the Distortion palette (next time you open the same image, or an image taken with the same combo of camera and lens, you will have to download and install the relevant DxO Optics Module again).When EXIF metadata is missing If for some reason DxO ViewPoint cannot find the EXIF metadata information it needs, a dialog box will ask you to locate the original image in order to retrieve the missing information.Open the image in DxO ViewPoint. If a dialogue box in the Distortion palette requests access to the original file, click on Open original image. Click Open in the dialog box that appears in the DxO ViewPoint window. A system dialog will appear to help you locate the original. You will need to find the JPEG or RAW image file that was loaded directly from your camera before processing. After finding and selecting the original image, click on Open. If the corresponding DxO Optics Module is not already installed, a new dialogue box will open and prompt you to download it (if available); otherwise, it will display the information about the shooting equipment and the name of the original file. Manually correcting distortion If your shooting equipment is not supported by a DxO Optics Module, you can manually correct your image. Distortion palette, manual correctionOpen an image in DxO ViewPoint by clicking File > Open, or drag and drop the image into the application window. In the Distortion palette, click the Manual button (a circle with vertical markings). Depending on the type of distortion visible in the image, select either Barrel, Pincushion, or Fisheye. The correction will be applied immediately. If necessary, you can use the Intensity slider to fine-tune the correction. Correcting volume deformation About Volume DeformationThe deformation of a subject at the edge of an image is a geometric flaw that is frequently observed on interior, event, and wedding photos. Known as volume deformation, it frequently occurs when using a wide-angle, or wide-angle zoom, lens to photograph objects, people, or groups of people. Elements at the edges of the image appear distorted and stretched. Identify the type of volume deformation Look carefully at your image to determine the kind of distortion affecting it: If spherical objects close to the edge of your image appear stretched or flattened along a vertical or horizontal axis then your image is suffering from volume deformation. In this case, use the horizontal/vertical correction tool. If objects seem to be stretched towards the corners of the image, then you are dealing with diagonal volume deformation, in which case you will need to use the diagonal correction tool. Correcting horizontal/vertical deformationTo correct horizontal or vertical volume deformation:After opening your image in DxO ViewPoint, activate horizontal or vertical volume deformation correction by clicking the button on the left. The correction is automatically and immediately applied to the image.

The air, it is refracted away from the normal. Since light refracts when it changes mediums it can be aimed. Lenses are shaped so light is aimed at a focal point. 38 light from far away objectLenses The first telescope, designed and built by Galileo, used lenses to focus light from faraway objects, into Galileo’s eye. His telescope consisted of a concave lens and a convex lens. light from far away object convex lens concave lens Light rays are always refracted (bent) towards the thickest part of the lens. 39 Concave Lenses optical axis F • Concave lenses are thin in the middle and make light rays diverge (spread out). If the rays of light are traced back (dotted sight lines), they all intersect at the focal point (F) behind the lens. 40 Concave Lenses optical axis F •When doing geometric optics problems it is much simpler to draw the lens/mirror as a line so that the light relects/refracts at the line. This saves us from having to show the lights behavior inside the lens. Light rays that come in parallel to the optical axis diverge from the focal point. The light rays behave the same way if we ignore the thickness of the lens. 41 Concave Lenses F • optical axisLight rays that come in parallel to the optical axis still diverge from the focal point. 42 Concave Lens (example)optical axis F • The first ray comes in parallel to the optical axis and refracts from the focal point.

A geometric algebra reformulation of geometric optics

This means that the same ray diagrams used to describe those devices can be used to describe the images formed by the tissues in the eye, as well as to design devices such as eye glasses to correct our vision when needed. Activity This simple model of an eye shows how geometric optics applies to the formation of images in the human eye.Next Generation Science Standards®Disciplinary Core Ideas:PS4: Waves and their Applications in Technologies for Information Transfer (wave properties of light and electromagnetic radiation)ETS1: Engineering Design (corrective lenses, microscopes, telescopes, projectors)LS1.A: Structure and Function: Multicellular organism have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level.Crosscutting Concepts: Structure and Function (anatomy of the human eye) Materials White BalloonDouble Convex LensFlashlightPermanent Marker3 Ring Stands2 Universal Joints2 RingsBurette Clamp Safety Follow all established safety protocols for laboratory activities. Do not use lenses to focus light from the sun. Do not look directly into the sun or light sources. If you are substituting a strong light source that produces heat, do not touch the light source or place the light source near flammable materials. Procedure 1. Take standard balloon (a 9” white balloon works well) and partially inflate it. It should be inflated enough that the surface of the balloon is smooth with no bumps but not inflated so much that it pops when squeezed.2. Twist the balloon at the neck to pinch off the air.3. Stretch the mouth of the balloon over and around the double convex lens so that the lens is held in place in front of the balloon and light can pass through the lens. When you untwist the neck of the balloon, the lens should remain in place and no air should escape.
