Title: Optical element
Inventor: YUASA SATOSHI
IPC: G02F1/01
Filed: 1984-12-24
Abstract: PURPOSE:To obtain a clear image having high resolution by providing a liquid layer contg. a liquid and a colored polymer having characteristic for desorbing liquid at relatively high temp. and absorbing liquid at relatively low temp. CONSTITUTION:An optical element is formed by laminating a substrate 1, a liquid layer 2 contg. gel, and a transparent protecting plate 3. The layer 2 comprises a liquid and a coloring-matter-contg. polymer for absorbing and desorbing the liquid. The polymer swells absorbing external liquid at relatively low temp. but contracts desorbing the liquid at relatively high temp. When the polymer is not irradiated with infrared beam 5, the colored gel 4-2 remains in the swollen state, so the light 6-2 which passes through the gel 4-2 passes through the layer 2 where the concn. of the contained coloring material in the gel 4-2 is low. On one hand, when a specified position of the layer 2 is irradiated with the infrared beam 5, the position is heated and the colored gel 4-1 contracts desorbing the liquid. As the result, the concn. of the coloring matter contained in the gel 4-1 is increased, so the light 6-1 is almost completely absorbed. Since the gel is made to very fine particles, a clear image of high degree of resolution is obtd.

Filed: 1993-11-01
Abstract: PURPOSE:To easily and surely decrease the flares and ghosts generated by the internal reflected light of the optical system to a level substantially negligible in practicable use without a limitation of a design by providing the specific reflection part of the effective diameter of the optical system on the effective coupling part of which detrimental rays are made incident by reflection with an antireflection means. CONSTITUTION:The luminous flux imaged on a CCD image pickup plane 3a is reflected by its surface and while the luminous flux diameter thereof is widened, the luminous flux travels backward in the optical system and is reflected again in the specific reflection part 2. At this time, the luminous flux is converted by the curvature of the subject side face 4a of a combined lens 4 and is made incident as flare light of high intensity again on the CCD image pickup surface 3a. An antireflection film is formed over the entire surface of the subject side face 4a of the combined lens 4 including the specific reflection part 2. Then, the intensity of the reflected light is decreased to <=1/10 and the flare light is suppressed down to the level negligible for practicable use. The light transmitted through the specific reflection part 2 is absorbed by a light shielding mask 1 arranged on the subject side of the combined lens 4, by which trouble is prevented.
