Modeling and simulation of multi-color CCD detector under super-continuum laser jamming

Considering the spectral characteristics of super-continuum laser and the signal conversion mechanism of multi-color charge coupled-device (CCD) detector, the simulation model of multi-color CCD detector imaging under super-continuum laser jamming was built. On the basis of the working principle of multi-color CCD, the transfer and transport rules of saturated and crosstalk signal were theoretically analyzed. Then, according with the structure of multi-color CCD, the spatial distribution characteristic of laser energy on the CCD surface was studied with the aid of optical design software. Taking into account the above researches, the simulation model of monochromatic CCD saturation crosstalk effect interfered by super-continuum spectrum laser was established, based on this, combined with the CCD imaging multi-color visualization principle, it was realized to simulate the multi-color CCD output image interfered by super-continuum laser. Finally, the influence of different laser energy on the image quality of multi-color CCD was studied by introducing the image quality evaluation factor. Experimental result indicates that the laser power density is an important influence factor of the laser interference effect. As the laser energy increases, the image quality of the multi-color CCD decreases.
