A Single Aspheric Collimating Lens of the Laser Proximity Fuze
This paper investigates the problems of the large beam divergence angle and the short detection range in the launch system of laser proximity fuze. By analyzing the semiconductor lasers′ characteristics of the optical field and the characteristics of laser′s far-field divergence angle, according to aspheric optical design theory, single aspheric collimation lens is designed by using Zemax. The simulation results indicate that the laser beam divergences are compressed to 5 mrad and 2 mrad respectively. The quality of the beam shaping increases effectively, and the emission beam divergence angle is reduced as well as the system range is improved.
