An Accurate Exposure Time Measurement Method of CCD Cameras
In the shadow photograph system in ballistics range, the exposure time of the CCD cameras is a very important parameter. The method to measure the accurate exposure time of the CCD camera is suggested based on the short pulsed laser source, timing sequence control system, high speed photo- detector and oscilloscope with the precision of 0.1μs. This method solved the problem of no effective measurement method with high precision for this parameter. The accurate minimum exposure time of IGV-B4820 of company Imperx was tested by this method successfully.
