Abstract: A method of focusing the monochromatic radiation by means of phase modulation where the latter is carried out depending on the phase and intensity of the focused monochromatic radiation and on a predetermined intensity distribution in the focusing area, by means of establishing such a correlationship between the points of the focused wave front and the points of the focusing area, where to each point of the focused wave front corresponds one point of the focusing area. A device for implementation of the method comprises a reflecting (1) or transmitting plate provided on its surface with zones (5) each of them having a continuous relief (6), the height of which and the form of the zones are changing in correspondence with the phase and the intensity of the focused monochromatic radiation and with the predetermined intensity distribution of the focused radiation in the focusing area.

Abstract: A transparent Fresnel plate consisting of a number of prisms each of a fine ridge shape having an oblique surface, arranged parallel to each other on the surface is used to convert the width and direction of a beam of light. Solar light projected onto the surface of the Fresnel plate with the ridges is reflected from the oblique surfaces and is reduced in width and reflected from the incident light direction toward the reflected direction. A reflecting device to re-reflect the reflected light to a predetermined position, or a reflected light energy collecting device, is provided in the path of the reflected light. The Fresnel plate can also be used to introduce solar light into a housing. In this case, solar light rays having a narrow width are converted into light rays having a wide width. The Fresnel plate can also be used as a blinker or a reflecting mirror for special purposes.

Abstract: A night vision sight is provided for use with a weapon, which includes an objective lens (16) and a non-inverting image intensifier tube (22) disposed along an optical axis (18), providing an intensified target image. The sight is focused by direct movement of the image intensifier tube relative to the fixed position of the objective lens. A reticle projector (50) is disposed orthogonal to the optical axis and provides a collimated reticle image, the reticle image providing an aiming point for the weapon. The reticle image is superimposed over the target image, which are reflected into an eyepiece (70) of the sight. The eyepiece has an axis (74) between the optical axis (18) and a sight line (14) passing through a pre-existing sight provided with the weapon. Adjustment of the apparent position of the reticle to compensate for azimuth and elevation is accomplished by moving the reticle projector about crossed cylindrical bearings.

Abstract: An article for presenting dye/pigment images therein comprising a substantially transparent viewing region (20); photodeveloped, printed, deposited or diffused dyes and/or pigments (21) in the viewing region; and a substrate region (22) adjacent to the viewing region. The outer surface (23) of the viewing region is configured in a relief pattern comprising microscopic, smooth, sharp pyramids (31), cones (48), or ridges (29), to provide a series of at least 3 surface reflections of any light impinging thereon, before the light travels toward the viewer's eyes. The reflectivity at any one surface reflection is less than about 5 % of normal incident light, so less than about 0.05 % (and preferably not more than 0.02 %) of such incident light is returned toward the viewer after 3 reflections, and less after (4). A viewer thus can see the dye/pigment images clearly from any direction and free from noticeable reflected light from the outer surface, and without loss of detail or contrast in dark areas.

Abstract: Known processes and devices for regulating the luminance of a surface capable of being illuminated cause changes of the colour temperature or local fluctuations of the lighting intensity. The disclosed process varies the light flux by generating uniformly distributed shadowings, so that a uniform distribution of the lighting intensity, as well as a uniform angular distribution of the luminous intensity, can be achieved. A particularly appropriated diaphragm is composed of a disk provided with several mutually parallel sickle-shaped openings.

Abstract: A deformable mirror system for reduction of projected image distortion in an optical system (30). A mirror (20) located near an intermediate image plane (25) is adapted to correct for ray direction. The distortion in the image is predetermined, and the mirror is contorted in a manner determined by the distortion to be corrected; relationships are prescribed for the desired contortion. Reduction in distortion can be achieved by placement of a mirror near the image plane; further reduction can be achieved by the placement of an additional contorted mirror at a subsequent image-forming aperture in the optical system. A particular example of an application for this system is aircraft simulators.

Abstract: A transparent optical film (30) made of a polymeric material has a first smooth surface (32) and a second structured surface (34) for providing a simulated beveled appearance. The structured surface (34) of the film is formed of a plurality of spaced parallel grooves, each groove being formed by a first facet which is substantially perpendicular to the first smooth surface and a second facet which makes an angle between 1 to 60 degrees with the first smooth surface. The film may be affixed to glass, the adhesive applied to the first smooth surface (32) or the second structured surface (72), to simulate beveled glass. Further, a leaded glass appearance or beveled mirror appearance may be simulated by vapor coating the optical film .
