摘　　要：探测器作为成像系统设计的"眼睛",其性能直接关系到成像系统的优劣。以高速小目标成像系统为例,介绍了实际应用中探测器选型的方法。以一特定系统为例,重点从探测器扫描方式,探测器结构及信噪比等方面做了详细介绍,并最终确定Kodak的KAI-4021作为该系统的选择。在实际的系统设计中,探测器的选择还综合考虑了许多其他因素,未在文中详述。As the eye of the imaging system,the sensor took an important role in the imaging system.With the high-speed small target imaging system as an example,the method of the choice of image sensor is introduced in the paper.Based on the research about the scanning schematics,structure of detectors and the comparison of SNR,Kodak KAI-4021 is chosen for the specific system.Although there are still other related points for the choice of the detectors,only key points are introduced.
