Abstract: The present invention pertains to systems and methods for the capture of information regarding scenes using single or multiple three-dimensional LADAR systems. Where multiple systems are included, those systems can be placed in different positions about the imaged scene such that each LADAR system provides different viewing perspectives and/or angles. In accordance with further embodiments, the single or multiple LADAR systems can include two-dimensional focal plane arrays, in addition to three-dimensional focal plane arrays, and associated light sources for obtaining three-dimensional information about a scene, including information regarding the contours of the objects within the scene. Processing of captured image information can be performed in real time, and processed scene information can include data frames that comprise three-dimensional and two-dimensional image data.

Abstract: An optical property measurement apparatus includes: a main body which includes a plane-shape surface that is so disposed as to face the display portion; an optical sensor which receives light directed from an opening that is formed through the plane-shape surface; and a support portion which is disposed on a side of the plane-shape surface and keeps a constant distance between the display portion and the plane-shape surface; wherein a light shield portion that is so disposed as to enclose a circumferential area of the opening of the plane-shape surface and shields entrance of light from a region other than a measurement target region of the display portion when the optical property is measured.

Abstract: A photometer device including an inlet passage for receiving a fluid such as an aerosol at a specified flow rate, an outlet passage separated from the inlet passage by a gap, and a radiation passage across the gap. The flow rate and the significant dimension of the inlet passage are set to produce a laminar flow of the aerosol. The gap and the significant dimension of the outlet passage are set to maintain a laminar flow of the aerosol across the gap to prevent contamination of the radiation passage.

Abstract: A symmetric monitor calibrator for mounting on a cathode ray tube or monitor with a surface. The calibrator has a case that holds electronic and optic components. Suction cups hold the calibrator to the surface, in which the suction cups are attached to the end of supporting elements that surround the case. At least three supporting elements with a common connecting point to form one support structure are connected to the top of the case. The supporting elements extend out creating a greater diameter than the case. The supporting elements and therefore suction cups uniformly surround the center point of the case to prevent rotation caused by the effects of gravity.

Abstract: An arrangement for measuring the power or energy of optical radiation of radiation sources, especially laser radiation is disclosed. It comprises a module defining an open or at least partially closed hollow space, wherein the inner walls or outer walls of the module are entirely or partially occupied by detectors for generating measurement signals which are proportional to the measured parameters of the radiation sources. The detectors are connected together in such a way that their generated measurement signals are further processed to form at least one resultant sum signal or the detectors are connected to a downstream processing device to form at least one resultant sum signal. This at least one resultant sum signal is relatively independent from the position, arrangement and radiating characteristic of the examined radiation source in the module. At least one opening or guide-through is provided in the module for inserting the radiation source to be examined.

Abstract: A laser power meter of the present invention including a laser power sensor and a power meter module is used for measuring the power level of a laser source in a minidisc recorder/player. The laser power sensor includes a photodetector and a variable resistor electrically connected together and housed in a cartridge-like housing that is equivalent in dimension to a minidisc used in the minidisc recorder/player. The laser power sensor is inserted into the minidisc recorder/player like a regular minidisc, thus allowing laser power readings without disassembling the recorder/player.

Abstract: An apparatus and method for the testing of materials by thermal oxidation is provided. The apparatus comprises a housing having at least one optic-isolated chamber. A photon counting photomultiplier and a heat source, for each optic-isolated chamber, are also provided within the housing. A cell, having a plurality of gas inputs and gas outlets, for holding a sample to be tested, is provided within the housing for each chamber. The gas inputs and outputs are distributed about the cell so as to disperse gas evenly about the material to be tested. The apparatus is used to count the number of photons which escape from a test sample as various oxidation conditions are employed.

Abstract: An improved bichromatic or polychromatic spectrophotometer comprising means enabling the user to electronically select which wavelength of a preselected pair of wavelengths shall serve as a "sample" wavelength, with the other then serving as a "reference" wavelength.
