Study of Receive Focusing Aspheric Optical Lens of Laser Fuze

This paper according to the problems of weak echo signal in the optical system of laser fuze. By analyzing the factors of measuring distance, combined with the specific requirements of laser fuze, according to aspheric optical design theory, using Optical Software of ZEMAX. Design single receive focusing lens of laser fuze. Simulation results show that the echo signal can be efficiently brought together. Finally, according to the design, non-spherical lens is processed. The experimental results show it has a clear echo signal when detection range is 18 m.
