對于低照度、高速運(yùn)動(dòng)物體等的測量拍攝場合，往往需要高靈敏度的線陣CCD相機(jī)。
本文介紹了一款高靈敏度的線陣相機(jī)的研制方案，相機(jī)的線陣CCD芯片采用DALSA公司的IT-F6，它具有96級TDI功能，動(dòng)態(tài)范圍3600：1，經(jīng)試驗(yàn)，靈敏度比一般的線陣CCD相機(jī)提高了約20倍，大幅度提高了系統(tǒng)的整體響應(yīng)水平。在靶場測試中，對距離5米外的7.2mm高速子彈彈丸可以清楚捕捉，在高靈敏度的探測場合具有廣闊的應(yīng)用前景。

Abstract: High-speed applications under low light condition requires high sensitivity line
scan CCD camera. This paper introduces a kind of project to design high sensitivity line scan
CCD camera with DALSA’s IT-F6 stage selectable TDI Image sensor. The IT-F6 has 96 TDI
stages and 3600:1 dynamic range. The experiment indicates that the IT-F6 camera increase
the sensitivity 20 times than normal line scan CCD. In the range testing, the camera can
acquire the 7.62mm bullet image from five meter. So this type of camera will have wide
prospect in future.
