Paper Abstract

A numerical modeling of heterodyne efficiency of coherent laser imaging system at nonlinear scanning has been developed on the basis of Monte-Carlo method. A hysteresis effect of receiving field of view (FOV) has been analyzed at high-speed nonlinear scanning. The numerical mathematical modeling for coherent nonlinear scanning laser imaging system has been conducted at the nonlinear harmonic scanning with 160Hz frequency; 64x32 pixels image size and 10 frames per second. The numerical modeling showed that imaging pixels with 20% threshold of heterodyne efficiency were about 17 at the 20dB SNR, 10 frames per second and 2400m detecting distance.
