Spot Image Processing and Simulation of the Laser Proximity Fuze
This paper investigates the problems of the large beam divergence angle and short detection range in the launch system of laser proximity fuze. By analyzing the factors of measuring distance in laser proximity fuze, combined with characteristics of lasers far-field divergence angle, and according to aspheric optical design theory, we carry out image processing and simulation of laser spot by using ZEMAX. The simulation results indicate that the laser beam divergence is compressed respectively to 4.5mrad and 2mrad, and the spot is reduced and the energy is concentrated. Finally, according to the design, a non-spherical lens is processed. The experimental results show it has a clear echo signal when detection range is 20m.
