本专利是一种供地球卫星使用的红外敏感器,该敏感器由外壳、输入光具、调制盘、会聚光具、探测器以及评价电路等组成。输入光具将地球成象在一块成象平面上;位于输入光具成象平面上的调制盘的直径与地球的图象相一致,该调制盘是按预定的调制频率和调制幅度沿成象平面的一个方向往复运动的;会聚光具位于调制盘对着输入光的那一侧,它将输入光具的成象平面会聚在红外探测器上;评价电路根据红外探测器的输出信号确定地球卫星一轴线偏离地球标称直线的情况。这种红外敏感器的特点是,它装有调节装置,这些调节装置可以使会聚光具(8)和
This patent is an infrared sensor used by earth satellites. The sensor consists of a housing, an input light fixture, a modulation dish, a converging light fixture, a detector, and an evaluation circuit. The input light will image the Earth on an imaging plane; the diameter of the modulation disk on the input light imaging plane coincides with the image of the earth, which is imaged at a predetermined modulation frequency and modulation amplitude Reciprocating motion in one direction of the plane; the converging optical device is located on the side of the modulating disk facing the input light, and converges the imaging plane of the input optical device on the infrared detector; the evaluation circuit determines the earth according to the output signal of the infrared detector Satellite axis deviation from the Earth’s nominal straight line situation. This infrared sensor is characterized by the fact that it is equipped with adjusting devices that allow the converging optics (8) and
