摘要： A method for identifying bad pixels in a matrix imaging sensor comprises moving the matrix sensor in a prescribed motion with respect to a background landscape (fig. 1, 10), acquiring a combined image of the landscape, and identifying bad pixels (16) in the matrix sensor from the combined image. The identification is aided by preferably applying filtering to the combined image. The prescribed motion is preferably rotation of the sensor or translation of the sensor around a circle, and the combined image includes a plurality of preferably similar landscape images. The identification of the bad pixels is performed on-line, in real-time, without requiring the use of a black body.

摘要： The invention relates to a cryogenic Joule Thompson system for cooling an IR sensor, which comprises: (a) a supply source for refrigerant gas; (b) an orifice through which said refrigerant gas flows to cool said IR sensor; (c) valve at said orifice location for closing or opening said orifice, the rate of opening of the orifice by said valve determines the rate of discharge of the refrigerant gas through said opening; (d) a bellows containing gas, said bellows is thermally coupled to said sensor, thereby to cause expansion or contraction of the bellows depending on the sensor temperature; and (e) a displacement rod, one end of which is rigidly connected to the bellows and the other end of which is connected to said valve, thereby to cause the rate of closure of the orifice by said valve to depend on the level of expansion of said bellows; wherein the system further comprises: (f) a resistor which is thermally coupled to said bellows; (g) a temperature measuring element for measuring the temperature of said IR sensor, and providing the temperature measurements to a processor; (h) a processor for receiving said temperature measurements, for detecting a state of sensor temperature increase after a period of said orifice closure or low refrigerant discharge rate below a predefined value, and for activating a current flow through said resistor any time when said state is determined, thereby to cause a boosted expansion of the bellows and acceleration of the opening of the orifice by said valve.
