红外小光点检测系统是重要的检测设备,它可用于检测红外器件光敏面大小、均匀性、多元器件的一致性及串音情况。这对于提高红外系统特别是以探测器为视场光阑的系统搜索和跟踪精度,提高成像系统的清晰度都具有重要意义。红外小光点系统首先要检测光斑弥散圆大小,才能投入使用。迄今为止,几乎所有的红外光学系统的装校和检测都是在可见光谱区进行。这就要求光学系统只能设计成反射系统。随着红外仪器发展,红外透镜已经被采用;在反射系统中常常要加红外波段滤光片;中红外以上的探测器往往都带有透红外而不透可见光的窗口。带有这些光学零件的红外系统,装调和检测不能在可见光谱区进行。有人曾经采用 Infrared small spot detection system is an important testing equipment, which can be used to detect infrared device photosensitive surface size, uniformity, multi-component consistency and crosstalk situation. This is of great significance for improving the system search and tracking accuracy of the infrared system, especially the detector as a field stop, and improving the definition of the imaging system. Infrared small spot system must first detect the size of spot diffuse circle, can be put into use. To date, almost all infrared optical systems have been installed and tested in the visible region. This requires that the optical system can only be designed as a reflective system. With the development of infrared instruments, infrared lenses have been used; in the reflection system, infrared filters are often added; detectors above mid-infrared often have windows that are transparent to infrared and not visible. Infrared systems with these optical components must not be installed or detected in the visible region of the spectrum. Someone used it
