Abstract: A guidance system for a missile performs a method for guiding the missile. The guidance system includes a target detector and a window between a target and the target detector. The window including a first pane, a second pane and a channel between the first pane from the second pane. Radiation from the target passes through the window including the first pane, the second pane and the channel to be detected at the target detector. A gas is transported through the channel between the first pane and the second pane to control a temperature of the window.

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 system for measuring light intensity distribution is provided and set in a vacuum environment. The system for measuring light intensity distribution comprises a carbon nanotube array located on a surface of a substrate, a reflector, an imaging element and a cooling device. The substrate is cooled by the cooling device to make a contacting surface between the substrate and the carbon nanotube array maintain a constant temperature. The carbon nanotube array is irradiated by a light source to make the carbon nanotube array radiate a visible light, and the substrate is continuously cooled to make the contact surface between the substrate and the carbon nanotube array maintain the constant temperature. The visible light is reflected with the reflector. The visible light reflected by the reflector is imaged with the imaging element to obtain the light intensity distribution of the light source.

Abstract: An apparatus includes a chamber, a first heat exchanger, an adapter, and a second heat exchanger. The first heat exchanger includes a cold finger positioned within the chamber. The second heat exchanger is positioned around an adapter and within the chamber. The second heat exchanger is a counter flow heat exchanger to precool refrigerant entering a Joule-Thomson valve. The adapter is positioned between the cold finger and the second heat exchanger. The adapter transfers heat from a thermal load to both the cold finger and the refrigerant emitted from the Joule-Thomson valve.

Abstract: A calibration system is provided including an aperture layer, a lens layer, an optical filter, a pixel layer and a regulator. The aperture layer defines a calibration aperture. The lens layer includes a calibration lens substantially axially aligned with the calibration aperture. The optical filter is adjacent the lens layer opposite the aperture layer. The pixel layer is adjacent the optical filter opposite the lens layer and includes a calibration pixel substantially axially aligned with the calibration lens. The calibration pixel detects light power of an illumination source that outputs a band of wavelengths of light as a function of a parameter. The regulator modifies the parameter of the illumination source based on a light power detected by the calibration pixel.

Abstract: An infrared sensor assembly for sensing infrared radiation from an object is disclosed. The infrared sensor assembly comprises a sensor array comprising a plurality of sensing elements, provided on or embedded in a substrate extending in a substrate plane. The sensor array comprises at least two infrared sensing elements, each infrared sensing element having a radiation responsive element providing a proportionate electrical signal in response to infrared radiation incident thereto and at least two blind sensing elements, at least one blind sensing element being interspersed among the at least two sensing elements, each blind sensing element being shielded from incident infrared radiation from the object and providing a proportionate electrical signal in response to parasitic thermal fluxes. The output of the sensor array is a function of the infrared sensing elements and of the blind sensing elements such that parasitic thermal fluxes are at least partly compensated for.
