OPTICS sa BINOCULAR sa CAMERA LENS sa COLOR sa FIBER OPTICS sa HOLOGRAPHY & LASER PHOTOGRAPHY sa INTERFEROMETRY sa KALEIDOSCOPE sa LIGHT sa MAGNIFIER sa MICROSCOPE sa OPTICAL ILLUSION sa OPTICAL INPUT EQUIPMENT sa OPTICAL PRINTING sa OPTOELECTRONIC DEVICE sa PERISCOPE sa PHOTOGRAPHY sa POLARIZED LIGHT sa PRISM sa STEREO IMAGING sa TELESCOPE xx LIGHT xx PHYSICS xx SCIENCE How to engage in observing and recording atmospheric optics. Part 1. Formerly called meteorological optics, it is simply the study of the multitudinous visual effects our atmosphere creates on light received from the sun. How to engage in observing and recording atmospheric optics. Part 2. Homemade refraction tank allows simulation of moving lights seen in the night sky under atmospheric temperature inversions, one explanation for UFO sightings. Moire patterns provide both recreation and some analogues for solving problems. Nomogram for determining the distance at which an object must be placed from a lens of known focal length so that its image will come to focus at a specified distance on the other side of the lens. Projecting moire patterns on 3-dimensional objects and photographing the results. How to make cylindrical and conical anamorphoscopes. Also includes instructions for making drawings using the geometrical technique and with the use of an enlarger or 35mm slide projector. (Anamorphic art is realistic art that has been grossly distorted in projection. By viewing the distortion through an anamorphoscope the image is reflected undistorted.) How to make a ruling engine that generates diffraction gratings of top optical quality. Observations on grinding glass by hand (free abrasive grinding) with suggestions for preventing scratches. A look at some classic visual diversions that were popular in the 19th century (moire effects, the kaleidoscope and the stereoscope). Includes information on duplicating moire pattern systems, how to make a kaleidoscope and how to make your own stereoscope and stereo cards from old Polaroid snapshots. Investigating the supernumary arcs (extra bands of color) found in some rainbows. The amateur scientist. Anamorphic pictures (photographs). Distorted views from which distortion can be removed. Experiments with a gradient-index (GRIN) lens in which the index of refraction varies internally. Simple optical experiments in which spatial filtering removes the unwanted information ("noise") from pictures. How to make lenses out of ice. Use them to start a fire, take a picture, etc. The amateur scientist. The optics of fly fishing. An analysis of how a fish views an object on (and above) the surface of the water. The impact of light refraction on line of sight. The amateur scientist. How the sun's reflection from water offers a means of calculating the slopes of waves. By photographing the reflection, one can compute the maximum slope without having to go out on the water. Experiments with reflections from a tilted mirror help illustrate the concepts. Layout and description of the "Hall of Mirrors" in Lucerne, Switzerland. Properties of the typical optical maze are discussed. Experiments on three-dimensional vision. Basic designs for a hyperscope, pseudoscope, and rhombus device are included. Reflections from a water surface display some curious optical properties. Reflections from a shiny ball. An analysis of the distorted images seen in Christmas-tree ornaments and other reflecting balls. The colors seen in the sky offer lessons in optical scattering. How light interracts with molecules and airborne particles. A drop of water becomes a gateway into the world of "catastrophe optics". A study of light patterns caused when light passes through a drop of water attached to a glass surface. Optical ray-tracing on a microcomputer. Short BASIC program traces a meridional light ray through an optical system. Any combination of lens and mirror surfaces are allowed. Build a simple optical instrument to view diffraction patterns. How to simulate the concept of a "gravitational lens" and show the effect. A field guide to atmospheric optics. Includes rainbows, halo phenomena, coronas, glories, low suns and twilights. Warning on potential health hazards for optical fabricators who work with diamond cutting and surfacing equipment. | |||||||||
