Modeling and Simulation Analysis for Crosstalk Effects and Secondary Spots of Laser Irradiation on TDI-CCD Camera
Based on push broom linear TDI-CCD imaging system, the principle of charge storage and signal transfer process was studied. According to the mechanism of saturation and crosstalk phenomenon induced by different continuous laser conditions, the crosstalk effects model was established. The modeling and simulation process for secondary spot was included. With an optical ray tracing model, the irradiant distribution of the imaging result was simulated when continuous laser jamming the satellite-borne infrared camera. Some general quality factors on imaging results were selected to qualitatively evaluate output images with given laser irradiant angles. The research indicates that the laser jamming result is different as the laser incident angle changes. At the given condition of 1.064 μm off-axis laser, when the laser incident angle differs from 2.86° to 2.89°, the secondary spot appears; When the laser power density is increased by 1~4 times, the percent of the crosstalk areas after laser jamming raises to some extent.
