Description
技术领域technical field

光电探测器的原理是由辐射引起被照射材料电导率发生改变。光电探测器在军事和国民经济的各个领域有广泛用途。在可见光或近红外波段主要用于射线测量和探测、工业自动控制、光度计量等；在红外波段主要用于导弹制导、红外热成像、红外遥感等方面。光电导体的另一应用是用它做摄像管靶面。为了避免光生载流子扩散引起图像模糊，连续薄膜靶面都用高阻多晶材料，如PbS-PbO、Sb2S3等。其他材料可采取镶嵌靶面的方法，整个靶面由约10万个单独探测器组成。光电探测器的安装场景较多，在有些安装场合收到安装底座或者整体框架会产生角度移动，从而对光电探测器的角度发生变化，从而对辐射的接收角度产生变化，从而影响探测效果。The principle of a photodetector is that radiation causes a change in the conductivity of the irradiated material. Photodetectors are widely used in various fields of military and national economy. In the visible or near-infrared band, it is mainly used for ray measurement and detection, industrial automatic control, photometry, etc.; in the infrared band, it is mainly used for missile guidance, infrared thermal imaging, infrared remote sensing, etc. Another application of the photoconductor is to use it as the target surface of the camera tube. In order to avoid image blurring caused by the diffusion of photogenerated carriers, high-resistance polycrystalline materials, such as PbS-PbO, Sb2S3, etc., are used on the continuous film target surface. Other materials can adopt the method of inlaying the target surface, and the entire target surface is composed of about 100,000 individual detectors. There are many installation scenarios for photodetectors. In some installation occasions, receiving the installation base or the overall frame will cause angular movement, which will change the angle of the photodetector, thereby changing the receiving angle of radiation, thus affecting the detection effect.
