Comparative study on saturation effect of 1.06 μm laser jamming CCD and CMOS cameras

To compare the jamming effect of laser on charged-coupled device (CCD) and complementary metal-oxide semiconductor （CMOS） imagers, jamming experiments with the wavelength of the 1.06 m high-repetition-rate laser were conducted. The relationships of the two cameras- laser incident power with the jamming effective area, saturated pixel number and the imaging correlation were analyzed individually. The experiment results show that the laser power threshold of one pixel saturation of CMOS camera is 20 times than CCD camera; in order to reach the same jamming effective area, the laser power of CMOS camera is 10~100 times higher than the CCD camera; and to reach the same saturation pixel, the laser power of CMOS camera is 10~60 times higher than the CCD camera. Therefore, the CMOS camera is better than CCD camera on the antijamming of the 1.06m laser.
