Abstract

Due to the high reflectivity of the resistor array in the target scene generator (TSG), the narcissus effect caused by the resistor array is notorious. Based on the paraxial analysis of the resistor array, the telecentric structure in the image space is proposed to reduce the narcissus effect induced by the resistor array. A TSG with the telecentric structure in the image space and a TSG with the nontelecentric structure in the image space, which have same system parameters, are designed and optimized. The nonsequential ray tracing technique is used for both TSGs to evaluate the narcissus effect induced by the resistor array. The simulation results show that using a telecentric structure in the imaging space is an effective method to suppress the narcissus signal caused by the resistor array.
