In order to research the hard damage effect on visible light CCD imaging system of off-band laser irradiation, one type of visible light imaging camera was irradiated by a continuous-wave chemical oxygen-iodine laser. Experiments with different camera aperture sizes were carried out. It was found that if aperture size became smaller, the hard damage would be more unlikely to happen, and the reason for this phenomenon was described. The hard damage threshold of the CCD was 5.5×104 W/cm2. Based on the CCD microscopic images, a preliminary discussion on the mechanism of hard damage was made.
