Embodiment Construction

[0039] The non-uniformity correction device of the embodiment of the present invention and the method for correcting the non-uniformity of an infrared detector using the device will be described in detail below with reference to the accompanying drawings.

[0040] refer to figure 1 with figure 2 , in one embodiment of the present invention, a device for correcting the non-uniformity of the infrared detector may include a plurality of thermostats (for example, figure 1 with figure 2 101, 102 and 103 in), displacement motor platforms (for example, figure 1 with figure 2 2 in ) and multiple boldfaces (eg, figure 1 with figure 2 301, 302 and 303 in ).

[0041] The plurality of thermostats can be along a first direction (for example, figure 1 with figure 2 Arranged in the direction indicated by the arrow A in). Each incubator houses multiple infrared detector test setups (e.g., figure 1 with figure 2 104 in ). The plurality of infrared detector testing devices are...

Abstract

The embodiment of the invention discloses a non-uniformity correction device and a method for correcting the non-uniformity of an infrared detector using the non-uniformity correction device. The device is equipped with a plurality of thermostats and a plurality of black bodies of different temperatures, and the displacement motor can control the plurality of black bodies to move to the detection range of the infrared detector testing device in each thermostat in turn, so that these infrared detectors can be tested The device can sequentially use multiple black bodies to correct the non-uniformity of the infrared detectors inside it. In this way, multi-point calibration of the infrared detectors in each infrared detector testing device can be realized conveniently.

Description

technical field [0001] The invention relates to the field of infrared detectors, in particular to a non-uniformity correction device and a method for correcting the non-uniformity of infrared detectors using the device. Background technique [0002] At present, due to the limitations of the infrared detector manufacturing process, it is difficult to ensure that the response performance of each pixel is completely consistent in the specific production, which will lead to various unevenness of the image in the actual imaging. However, the common processing method nowadays is to use one-point, two-point or even multi-point correction methods to artificially calibrate each pixel response of the detector under uniform black body radiation. Theoretically speaking, the larger the number of calibration points is, the more accurate the calibration results will be. However, considering the actual software and hardware conditions, the two-point calibration method is mostly used for ca...
