We really see images. 7 converge: come togetherImages are formed when light rays converge. converge: come together 8 When light rays go straight into our eyes, we see an image in the same spot as the object. object & image 9 Mirrors It is possible to see images when converging light rays reflect off of mirrors. image object 10 Reflection (bouncing light)Mirror normal incident ray reflected ray Reflection is when light changes direction by bouncing off a surface. 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.

Wrap around the X and Y axis.Threshold is only available when Use Edge Rays has been enabled. This sets the pixel values that are affected by the light rays. Lower values apply the light rays to more pixels in the object, while higher values will apply the light rays to fewer pixels.Apply Mode allows you to select how the rays composite on the object or scene. You can select Behind, In Front, Screen and Add.In this example the light rays have been composited Behind and In Front of the object to produce very different results.Mix With Original blends the light ray effect back with the unfiltered input object.Shimmer TabShimmer creates additional flickering rays of light eminating from the source point.Amount controls the number of shimmering rays. Higher values will produce more streaks.Detail controls the sharpness of the shimmer. Lower values will produce fainter streaks, while higher values will produce more detailed streaks.Rate controls the speed of the shimmer. Higher vaules will produce faster, more noticible shimmering, while lower values will produce subtle shimmering.Random Seed simply adjusts the randomness of the shimmering. You can use this parameter to introduce more or less randomness into the animation.Smoke TabHere we can create detailed fog and clouding in our light rays by adding a foggy appearance to the light source.Intensity increases or decreases the intensity of the smoke visible in the scene. Higher values will produce more intense smoke effects, while lower values will produce more subtle effects.Rate controls the speed of the smoke’s evolution. Higher values will produce faster moving smoke, while a value of zero will produce no movement in the smoke.Rotate changes the angle of the fog.Scale changes the scale of the fog, with smaller values producing more detailed smoke effects.Random Seed introduces random patterns to the fog effect.Color allows you 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.

(given by the baseline) and the spatial resolution. The former defines the maximum distance between the change of perspective within a light field, while the latter affects visual realism. When recovering 3D from (2D) images, there are cues in the image providing 3D information, such as shading, texture, focus, motion, and perspective [28]. However, existing 2D displays fail to deliver a fully immersive visual experience as critical perceptual cues such as vergence and accommodation, associated with realistic 3D perception, are not provided. In contrast, specific 3D displays would be able to replicate the rays of light (light field), including the directional and color components, to simultaneous viewers in a content-related interaction use case, for example.The challenge of light field displays is to convey/recreate the light rays that come from the scene to the viewer’s eyes. Pixels in 2D displays convey the same color light in all directions, despite the viewer’s point of view, while 3D displays convey unique color rays in each direction in a bundle of rays (3D pixels). To reproduce these directional light rays as accurately as possible, the display needs acuity (spatial resolution), several possible viewing angles of the light rays, and their associated depth.Light field displays cannot reproduce an infinite number of light rays while having to be able to address the vergence–accommodation conflict [29]. Considering the two-plane parametrization (Sect. ), the spatial resolution (2D image size) and the angular resolution (2D array view spacing: horizontal and vertical), the display resolution and FoV will establish a volume where the scene objects are exhibited. So, the observer will have to be at a ‘valid’ point of view to ‘see’ the object [30, 31]. The visualization techniques and output devices may allow an extended depth of field, refocusing, and 3D views. Horizontal-parallax-only and vertical-parallax-only displays limit the practical.

How lenses and mirrors affect light and vision Explanation of the refraction of light through different lenses. Encyclopædia Britannica, Inc. Transcript We see objects when light waves bounce off their surfaces and travel toward our eyes. This behavior of light is called reflection. Opaque objects, other than mirrors, will also absorb light rays. They reflect only the colors of light that they appear to be and absorb the other wavelengths of colored light.When light waves pass through transparent, or see-through, objects, another behavior of light called refraction occurs. As a light wave enters a new transparent substance – at an angle other than 90 degrees – it bends, or refracts. Refraction often causes objects to look different when we view them through different transparent substances.Optics is the study of light. It includes the study of how visible light and the eye interact to produce sight. Mirrors and lenses are important optical tools because they reflect and refract light.Eyeglasses, magnifying glasses, telescopes, and binoculars all have lenses or mirrors that control how light enters the eye. These optical instruments can greatly extend human vision.All mirrors are opaque and completely reflect light. They can be flat, concave, or convex in shape.All lenses, including the lenses in our eyes, are transparent and refract light. Many of us depend on corrective lenses to function independently. Lenses can be concave or convex. A lens’s shape determines the images it forms.When parallel rays of light enter a concave lens, the light waves refract outward, or spread out. The light rays refract twice: first when entering the lens and second when leaving the lens. Only the light rays passing through the center of the lens remain straight. Parallel light rays that pass through a concave lens do not meet. Viewing an object through a concave lens will
