Abstract: The invention provides an optical attenuator having a pair of substantially parallel mirrors that attenuate an optical signal based, at least in part, on the rotation angle of the mirrors. When the pair or mirrors is in a predetermined position, an input optical signal is directed from an input port to an output port with a minimum insertion loss. As the pair of mirrors is rotated, the optical signal is shifted parallelly, which provides increased insertion loss and an attenuated signal at the output port. The pair of mirrors can be rotated, for example, with a stepper motor, or other device.

Abstract: The present invention is directed to an optical system for measurement of a three dimensional device. The optical system is designed and configured to meet telecentric and f-.theta. requirements. The system employs primary and secondary mirrors operating in conjunction with a tertiary deflector mounted on a pivot. Light from a light source produces a beam which is deflected off the deflector and the secondary and primary reflectors respectively. The beam is then transmitted to the surface of the object to be measured. Deflection of the tertiary deflector on the pivot results in scanning of the light beam across the surface of the object to be measured.

Abstract: For a person who for whatever reason is required to remain prone, i.e. lying face downward, for long periods of time, a parallelepiped housing has a cushion top for comfortably supporting the head of the person. The cushion top defines an opening ("view port") through which the person can look into the housing. Within the housing is a series of mirrors for redirecting the person's field of vision from downward to forward through an front aperture defined by the housing. Preferably the aperture is the absence of a front wall. A manually turned crank reachable by the person allows the person to selectively vertically adjust the his or her field of vision. In the preferred embodiment, the crank rotates a plurality of eccentric cams which pivot a mirror either forward or backward depending on the direction of rotation.

Abstract: An optical filter that uses multiple reflections to provide spectral bandpass filtering of ultraviolet, visible and infrared radiation with a very high transmission of wavelengths within a selected passband coupled with exceptional off-band rejection. The reflection filter uses dielectric-coated spherical reflectors or mirrors manufactured with absorbing glass substrates. The multiple-pass feature of the reflection filter is achieved using a traditional long-path absorption cell such as a White Cell or Wilkes Cell. The light transmitted through the reflection filter is only that light which has undergone multiple reflections as the wavelengths of high mirror reflectivity reflect off the dielectric-coated substrates. All remaining light at wavelengths corresponding to high mirror transmission is attenuated by absorption in the mirror substrate.

Abstract: An optical system for an optical character reader in which a camera, such as a TV camera, reads an image field in a document, includes at least one pair of mirrors which shift half of the image both laterally and vertically to convert a relatively long image, for example with a length to height aspect ratio of 1.5:8, into a rectangular image with a much lower aspect ratio, for example 3:4. Preferably two pairs of mirrors are used, so that the image light path for both parts of the image field is the same length. This optical system reshapes the image field from one having an aspect ratio which does not match the 3:4 aspect ratio of most cameras, such as camcorders, TV cameras, security and surveillance cameras and the like, into one that does, thus significantly simplifying the optical character reader, and lowering its cost.

Abstract: A new and improved laser light beam homogenizer for transforming a laser beam with spatially inhomogeneous intensity into a beam with a more nearly spatially uniform intensity pattern is presented. The light beam is diverged by a lens and presented to an integrator. The integrator transforms the beam into a beam with a more uniform illumination. The uniform illumination beam is then impinged on control optics to limit the divergence of the uniform beam and control higher order distortion in the system. This beam may then be illuminated at a predetermined distance by a projecting optic lens. The laser light beam homogenizer of this invention is particularly well suited for use in an imaging lidar system.

Abstract: The housing (10), which is inserted between the magnification selector (7) and the ocular tube (8) of a microscope, accommodates a pivotable mirror (22) which is normally placed outside the beam path of the microscope, but which by actuating a lever (17) can be pivoted into the beam path in order to deliver the latter through a photo cone (13) to a camera (14). By actuating the lever (17), the camera (14) is released after the required chronological delay in order to take a picture of the object, e.g. an eye (4). A diaphragm arrangement, which can be brought into the preselected position for the exposure as well by actuation of the lever (17), is disposed at the entry of the housing (10), i.e. directly adjacent the magnification selector (7). Due to the full availability of the light and the advantageous position and adjustability of the diaphragm, optimum conditions exist both for observation and for photographical exposures.

Abstract: The self-retracting sighting device for an onboard optoelectronic localization and identification system has an elongated shape such that its rotation axis in elevation, beneath the fuselage of the carrier, is off-centered with respect to the input pupil. For the bottom line of sight, the device protrudes out of the fuselage to a major extent but, when the elevation angle increases, the device self-retracts beneath the fuselage, the top lines of sight being obtained without hindrance to the pilot's visibility. By additional rotation about the elevation axis, the input pupil is completely retracted beneath the fuselage, that part of the sighting device that protrudes out of the fuselage being then at its minimum and having an aerodynamic shape. The device can be applied notably to carriers in which the pilot's visibility is essential, for example during the stages of touchdown on aircraft carriers.

The latter comprises a pair of mutually-facing flat mirrors supported by a frame in spaced-apart relationship, the mirrors diverging downwardly. The frame is in the form of a casing opening downwardly, with a top wall provided with an opening surrounding the rim of a lamp shade, the frame being rotatably supported by the lamp shade. The base of the lamp is fixed to a stationary structure near the bed. The lamp is of the type in which the lamp shade can be adjustably positioned in space, so as to support the viewer in the proper position and at the proper angle with respect to the user and the television apparatus. The lamp can be used for reading or the like since the light bulb is exposed in the space between the two mirrors.
