Out-field laser jamming experiment of single CCD colour imaging system irradiated by multi-wavelength laser (750-970 nm) was done. Laser jamming effects of colour CCD imaging system with different irradiating conditions were measured at 1.3 km. Laser jamming model was set up
and theoretical proving and analysis on experimental results were completed. Theoretical and experimental results show that the jamming effect of laser on colour CCD imaging system is obvious
CCD surface appears obvious light saturation and crosstalk phenomena. The light saturation phenomenon is caused by laser diffraction effect. In addition
laser jamming effect and light saturation gradually enhance with the increasing of the laser power density to target. When the laser power density to target of single wavelength 750 nm laser is 4.2 kW/cm
2
the light saturation area of CCD surface is 0.88 mm0.97 mm. When the laser power density to target of multi-wavelength laser is 20.7 kW/cm
2
CCD device appears the whole target saturation. The simulation results are coincident with the experimental results
and it proves that the laser jamming model is correct. The simulation results for far-field laser jamming show that the laser jamming effect gradually weakens with the increasing of laser jamming distance.
