Abstract: An illumination device and method are provided herein for calibrating individual LEDs in the illumination device to obtain a desired luminous flux and a desired chromaticity of the device over changes in drive current, temperature, and over time as the LEDs age. The calibration method may include subjecting the illumination device to a first ambient temperature, successively applying at least three different drive currents to a first LED to produce illumination at three or more different levels of brightness, obtaining a plurality of optical measurements from the illumination produced by the first LED at each of the at least three different drive currents, obtaining a plurality of electrical measurements from the photodetector and storing results of the obtaining steps within the illumination device to calibrate the first LED at the first ambient temperature. The plurality of optical measurements may generally include luminous flux and chromaticity, the plurality of electrical measurements may generally include induced photocurrents and forward voltages, and the calibration method steps may be repeated for each LED included within the illumination device and upon subjecting the illumination device to a second ambient temperature.

Abstract: A sensor device has a metal sensor housing with a housing base coupled to a frame base of a metal optical frame. A device mounting plate is orthogonal to the frame base. A securing device secures an optical communication device to the device mounting plate. A barrel mounting channel has first and second sidewalls, each extending obliquely to the frame base and defining a linear translation pathway along the frame base for a metal lens barrel. A fastener secures the metal lens barrel to the first and second sidewalls. A glass lens is in contact with three protrusions extending outward from an inner annular surface of the lens barrel. The optical communication device is configured to be in optical communication with the lens and is secured in a particular position in a translation plane mutually defined by the device mounting plate and the optical communication device.

Abstract: An electromagnetic radiation detection system includes a detection circuit detecting an electromagnetic radiation and supplying a representative electrical signal. A cold table supports the detection circuit. A thermally insulating support supports the cold table. It includes an enclosure defining a closed volume and provided with a bottom, a top and a side wall connecting the bottom and the top. The thermally insulating support mechanically connects the cold table with the bottom of the enclosure. A cooler is mechanically connected to the enclosure and configured to cool the detection circuit. The cooler is mechanically fastened onto the side wall of the enclosure and thermally connected to the detection circuit by means of a thermal connector connecting the cooler and the cold table and the cold shield.

Abstract: An optical sensor includes a support layer, a thermoelectric conversion material portion disposed on the support layer and including a strip-shaped first material layer that converts thermal energy into electrical energy and a strip-shaped second material layer that is electrically conductive, and a light absorbing film disposed on the thermoelectric conversion material portion to form a temperature difference in a longitudinal direction of the first material layer. The first material layer includes a first region and a second region. The second material layer includes a third region and a fourth region connected to the second region. The optical sensor further includes a first electrode electrically connected to the first region, and a second electrode disposed apart from the first electrode and electrically connected to the third region. The first material layer has a width, perpendicular to the longitudinal direction, of 0.1 μm or more.

Abstract: A system for determining the profile of a laser beam includes a detector having a thermochromic liquid crystal film (TLCF) in thermal communication with a heat spreader and a thermoelectric cooler. The liquid crystal film has a thermochromic response such that heating of the film by a received laser beam creates a detectable color response at the film. The system also includes an image sensor and a controller configured to output an operating current for the TEC and receive images from the sensor. The system can selectively vary the temperature set point of the TEC to change the steady state temperature of the TLCF to examine the full intensity profile of the received beam even when the temperature response bandwidth of the TLCF is too narrow to display the full beam profile in a single color spot.

Abstract: A particle sensor is provided. The particle sensor includes a light projector that projects light to a detection area. A light receiver receives scattered light. The scattered light is light from the light projector that has been scattered by particles in the detection area. A first support supports the light receiver. A second support supports the light projector and has a linear expansion coefficient different from a linear expansion coefficient of the first support. The first support includes a first placement region in which the light receiver is disposed and a second placement region in which the second support is disposed. The first placement region and the second placement region are located at different distances from at least one of an optical axis of the light projector and an optical axis of the light receiver.
