Experimental study on disturbing effect of pulsed laser against array CCD imaging systems

In order to study the disturbing effect of pulsed laser against an array CCD, experiment of CCD imaging system disturbed by repeated pulse laser was carried out at short-distance. Crosstalk effect of the CCD was observed and recorded at an energy density of 2.97mJ/cm2 received by the CCD detector. When the electric shutter of the CCD vidicon was turned on, the images of excursion laser spots were found in the vertical direction of the laser radiation windows except for laser beam spot image. Operation principle of the electric shutter and the transfer mechanism of the CCD were analyzed. Phenomena of laser spot excursion were explained. Experimental results indicate that CCD images can be disturbed by the spot excursion caused by repeated pulse laser. The result lays the academic foundation and elementary experiment for CCD disturbed by repeated pulsed laser.
