It is an object to provide a reflector plate capable of suppressing coloring caused by interference and enhancing visibility. A plurality of first reflecting units 10 and a plurality of second reflecting units 11 are provided together. In this case, a reflecting plane 11a of the second reflecting unit 11 is set to be smaller in diameter and have smaller difference in in-plane height than those of a reflecting plane 11a of the first reflecting unit 10, and an arrangement interval between the second reflecting units 11 is set to be greater than that between the first reflecting units 10.

Provided is an optical multilayer structure having a simpler configuration, flexibility in selection of materials and improved reliability in wiring and capable of high-speed response even in a visible light range. A optical multilayer structure (1) comprises a first layer (11) being light-absorptive and making contact with a substrate (10), a gap portion (12) having as large a size as light interference phenomenon can occur and being capable of varying the size, and a second layer (13) being transparent in this order on the substrate (10). Where a complex refractive index of the first layer (11) is N1 (nulln1nullinullk1, n1 is a refractive index, k1 is an extinction coefficient, and i is an imaginary unit), a refractive index of the second layer (13) is n2, and a refractive index of an incident medium is 1.0, the optical multilayer structure (1) is configured so as to satisfy the following formula. 1 ( n 1 - n 2 2 + 1 2 ) 2 + k 1 2 - ( n 2 2 - 1 2 ) 2 = 0

An Adjustable Segmented Dual Function Mirror with video display (ASDFM) suitable for providing alternatively or simultaneously both a conventional reflected image and a video image under a wide range of ambient lighting condition is disclosed. The ASDFM comprises a two-dimensional connection of traditional mirror segments and dual function mirror segments. Each dual function mirror segment can be rotationally and adjustably connected to the rest of the ASDFM to achieve an optimal visually relevant image-to-ambient contrast for viewing. Alternatively, a position adjustable variable transmissivity screen, a controllable variable transmissivity film or a controllable variable reflectivity film can be included in a dual function mirror segment that is rigidly connected to the rest of the ASDFM for the same purpose. Numerous mechanical, fluid dynamical and electrical implementations are described.

A deformable mirror arrangement has a plurality of constraint mechanisms contacting a deformable mirror at specified contact positions. At least three of these constraint mechanisms are rigid body servo control mechanisms such as high-bandwidth servo control mechanisms, each including a force actuator contacting the mirror at a corresponding one of the contact positions, a position sensor assisting to measure position of the mirror and a servo control unit for controlling the force actuator.

A variable-profile optical device includes a light-transmission elastic member in which an elasticity of a first surface is set to be higher than that of a second surface disposed opposite to the first surface, wherein a pressure is applied to the second surface of the elastic member, so that the second surface of the elastic member is selectively deformed, and a focus distance may be varied.

A wing mirror for vehicles includes a reflector having a flat region to serve as a planar mirror, and two curved regions integrally formed on outer and bottom sides of the flat region to serve as convex mirrors so as to give a view of a wide angle to the driver and avoid blind side. Furthermore, the integral formation of the curved regions with the flat region allows an existing wing mirror to be changed from a conventional type into the inventive type simply by replacing with the inventive reflector.

This invention pertains to a multipass retroreflector and to a method for its operation. In a preferred embodiment, the retroreflector comprises three reflecting surfaces arranged at an angle to each other in the form of a prism that is triangular in cross-section and 1 to 2 ports through which an optical beam enters and/or exits. The method includes the step of admitting an optical beam into the retroreflector where the optical beam is reflected from the reflecting surfaces and exits parallel to the path of the incoming optical beam. The method also includes the steps of spacing and adjusting angular disposition and dimensions of the reflecting surfaces in order to change path length of the optical beam passing through the retroreflector. This spacing can be continuously scanned causing a large change in optical path length due to a small change in the position of the moving surface.

A heated mirror is provided. The mirror includes a plastic or glass substrate. A contact surface is provided for receiving a resistive heating layer. A plurality of spaced electrodes are electrically coupled to the resistive heating layer for inducing a current in the resistive heating layer to heat the mirror assembly. the substrate is polished in the direction of current flow through the resistive layer. The assembly may also include a separate reflective layer.

A mirror assembly has a pair of telescoping tubular supports extending between a support base and a mirror head to provide adjustment of the mirror head toward and away from the support base. Friction shoes within the tubular supports releasably hold such supports against unintentional telescoping movement. Cooperating stops on the telescoping supports limit outward movement of the mirror head and prevent complete separation of the telescoping supports. The tubular supports are hingedly attached to the support base for rotation about a vertical axis, and cooperating detents and spring elements on the supports and support base releasably hold the supports against rotation.

An electro-optical device includes a substrate; pixel electrodes disposed above the substrate; switching elements; an interlayer insulating film disposed at a position higher than the switching elements and lower than the pixel electrodes; contact holes, disposed in the insulating film, to connect the switching elements to the corresponding pixel electrodes; and filler, disposed in the corresponding contact holes, including a conductive material. Therefore, light leakage caused by vacant contact holes disposed in a layered structure on a substrate is reduced or prevented, thereby displaying a high-quality image.
