Abstract: A prism system and method for eliminating color aberration in an illumination system of a micro projector is disclosed. A light beam enters into a first prism through a light incident surface thereof and is further emitted through a light-emitting surface of the first prism. The light beam then enters into a second prism through a first interface thereof, passes through a second interface of the second prism and reaches a digital micromirror device (DMD). The light beam is reflected by the DMD so as to pass through the second interface and reach the first interface. The light beam is totally reflected by the first interface so as to be emitted through a third interface of the second prism. Therefore, the invention eliminates lateral color aberration that occurs in an active area of the DMD, reduces costs of illumination equipment and achieves a preferred projection effect.

Abstract: An artificial retinal system includes an external optical device having an image generator and a background light generator, and a retinal implant chip having a solar cell and a stimulus generator. The stimulus generator is disposed to receive a target image projected by the image generator and a background light provided by the background light generator, and receives the electrical power from the solar cell. The stimulus generator includes an image sensing stimulator operable to convert the target image into electrical stimuli, and a contrast enhancer for reducing effect of the background light on the electrical stimuli.

Abstract: An optical object distance simulation device for reducing total optical path includes: a lens, an achromatic lens set, a first image lens, and a second image lens. The achromatic lens set disposes beside one side of the lens, the first image lens disposes beside one side of the achromatic lens set, and the second image lens disposes beside one side of the first image lens. The achromatic lens set is composed of a first lens and a second lens. The first lens is a double-concave lens. The second lens is a double-convex lens. One concave face of the double-concave tightly contacts with one convex face of the double-convex lens. Therefore, the lens, the achromatic lens set, the first image lens, and the second image lens match with each other in order to simulate real object distance for reducing an object distance between a test camera lens and a corresponding chart.
