摘要： There is provided an improved night vision goggle having a housing containing an objective lens assembly, an image intensifier tube, a collimator assembly, a splitter member, and a pair of afocal telescopes. The optical axis of the afocal telescopes are offset from the optical axis of the collimator and objective lens assemblies. A pair of achromatic doublet lens assemblies are mounted side-by-side on the exit side of the collimator and near the entrance pupils of the telescopes. The optical axes of the doublet lens assemblies are coaxial with the optical axes of the telescopes. The achromatic doublet lens assemblies thus collect light from a sub-diameter, decentered aperture of the collimator assembly, and correct axial chromatic aberration in the telescopes.

摘要： A sinusoidal phase generated carrier is used to demodulate signal output from an interferometric sensor array. Optical signals input to the array are modulated with a sinusoid. Output signals are sampled and integrated over portions of a period of the phase generated carrier. A key to this method of sampling is the existence of pairs of signals associated with integration over two 180.degree. out-of-phase portions of the phase generated carrier. This invention is a four step method involves the implementation of two pairs of such signals to determine the phase shift in each sensor in the array.

摘要： A multi-function day/night observation, ranging, and sighting device includes a single objective lens group and a single eyepiece lens and provides an image of a scene. The single objective lens group leads to a visible-light first optical path and to an invisible-light second optical path. It will be understood that the terms visible-light and invisible-light are used merely to distinguish the two optical paths, and not as a limitation. In other words, some visible light will pass to the image intensifier tube, and this tube is capable of providing an image in response to light in the visible portion of the spectrum. On the other hand, some light in the infrared portion of the spectrum may pass along the visible-light optical path. As mentioned, the invisible-light second optical path includes an image intensifier tube providing a visible image. The first and second optical paths converge with visible images provided by each pathway being overlaid at a reticule plane. A single light path leads from the reticule plane to the eyepiece lens. A laser provides a pulse of laser light projected into the scene via the single objective lens, and the image intensifier tube is used as a detector for a portion of the laser light pulse reflected from an object in the scene in order to provide a laser range finding function. The device includes a light-emitting display visible through the eyepiece lens and providing ranging information superimposed over the image of the scene as seen by a user of the device. Methods of the device's operation are also disclosed.

摘要： A night vision device with an image intensifier tube includes an improved power supply which operates the image intensifier tube of the device according to a variable duty cycle either at a design voltage level for the tube or at a voltage level simulating a dark-field. This duty cycle variation is effected as a function of the current flow in the image intensifier tube in order to provide automatic brightness control and bright source protection. An improved service life for the image intensifier tube is achieved. Also, a microchannel plate of the image intensifier tube need not carry an ion barrier film, resulting in an improved light amplification for the image intensifier tube.

摘要： An apparatus for providing oxygen-enriched air at a first pressure and at a second pressure, the second pressure being greater than the first pressure. The apparatus comprises, in combination, a pressure swing adsorption system and a pressure intensifier. The pressure swing adsorption system for enriching the oxygen content of air has a pressure of at least the first pressure. The pressure swing adsorption system is adapted to provide oxygen-enriched air to a first outlet at the first pressure and to provide oxygen-enriched air to a pressure intensifier at the first pressure. The pressure intensifier pressurises the oxygen-enriched air and provides the oxygen-enriched air to a second outlet at the second pressure.
