Abstract: An infrared collector employs a concentrator formed of a plurality of spatially related gradient-indexed (GRIN) lenses and a photodetector, interconnected by optical fibers. Since the GRIN lenses are arranged on a hemispherical shell, the concentrator is relatively insensitive to the direction of the incoming infrared radiation. Optical fibers are used to connect the GRIN lenses to a photodetector, whereby assembly is simplified. The infrared detector in the collector of the present invention has a size that is significantly smaller than those used in conventional collectors. The concentrator has high optical gain, and therefore, is particularly well adapted for use in low-power portable systems. The arrangement is useful as a node in an infrared data network.

Abstract: A gonioradiometric scanning apparatus and method for measuring the near and/or far field radiation pattern of radiating optical sources such as laser diodes (LD), light emitting diodes (LED), optical fibers, flat panel displays, and luminaires is described. The scanning apparatus incorporates a deflector for selecting an azimuth angle through the optical source to be measured, a rotating apparatus which collects light while scanning about the source, an optical commutator, and a detector. The rotating apparatus comprises a cylindrical hub and an optical collector using either an optical fiber or a train of reflectors, such as mirrors or retro-reflectors. The optical collector provides a means for both collecting light and for directing the beam emanating from the deflector to a place opposite the detector at which optical commutation occurs. The reflector optical train, when employed, folds the optical path and increases the effective radius of measurement, so that large radius scans can be obtained in an instrument with compact geometry. Depending on the source geometry and the effective optical path, the light collection can be either in the near field or the far field of the source radiation pattern. For the case of the far field radiation pattern, it will also be possible to measure the near field radiation patterns by imaging the source onto the light collection surface.

Abstract: A movable plate 5 and torsion bars 6 are monolithically formed in a semiconductor substrate 2. A flat coil 7 is formed on peripheries of the movable plate 5 while a photodiode 8 is formed on a central portion of the movable plate 5. Permanent magnets 10A, 10B, 11A and 11B are provided on upper and lower spaces of the peripheries of the movable plate 5 while coils 12A and 12B for detecting a displacement angle of the movable plate 5 are provided on lower spaces of the peripheries of the movable plate 5. Flowing a current into the flat coil 7 generates a driving force depending on a relation with magnetic fields induced by the permanent magnets 10A, 10B, 11A and 11B, which makes the movable plate 5 to rotate axially around the torsion bars 6 to vary an orienting direction of an optical axis of the photodiode 8. The displacement angle of the optical axis is detectable by changes in mutual inductances between the flat coil 7 and the detection coils 12A and 12B, namely, changes in induction voltages of the detection coils 12A and 12B.

Abstract: A light sensor comprises optical filters, an interference filter and a photoelectric converting element which receives and photoelectrically converts light which has passed through the optical filters and the interference filter. An incident angle of the incident light on the interference filter can be changed so as to realize a desirable spectral sensitivity in a combination of the optical filters, the interference filter and the photoelectric converting element. The incident angle can be changed by a mounting structure that can rotate about an optical axis.

Abstract: A scanning system which obtains and displays the spatial energy distribution of a high power laser beam. The beam to be examined is directed toward two knife-edge mirrors arranged to pass only a thin vertical segment of the beam and to reflect the remainder of the beam to power absorbers. The mirrors are scanned across the beam, and a scanning disk having helical slots therein samples the vertical segment, and these samples are directed by means of a paraboloid mirror toward a detector responsive to the wavelength of the laser beam. The output of the detector is placed into storage and thereafter displayed on a high resolution color monitor with different colors representing different energy levels or as a simulated three dimensional display so that an operator may obtain an indication of the spatial energy distribution of the laser beam under examination.
