Abstract

The damage threshold of CCD’s black and white screen has been effectively measured in this paper. The visible array CCD is a type of photoelectric detector used at the visible wavelengths. The black and white screen of visible array CCD had been observed when it was irradiated by 532nm pulsed laser with low repetition frequency and high energy from a distance of 30m. The measurement method was proposed for the damage threshold of laser power density at the photosensitive surface when the black and white screen came into being. The gain of optical system was firstly designed to measure as 4.4×10³ by changing the repetition frequency of incident laser and adding the right attenuation slices in light path, and finally the damage threshold of CCD’s black and white screen was calculated as 4.5W/cm². The research fruit can provide the theoretical basis and data reference for carrying out the jamming and blinding photoelectric detector of high power laser.
