Evaluation of a novel integrated laser fuze receiving system

Abstract

Laser receiving system is an important part of laser fuze, but its working quality is very sensitive to severe overloading. As the common buffer isolation methods are difficult to apply in laser fuze receiving system, in this study, a high overload buffer isolation method of laser fuze receiving system is developed. Dynamic finite element analysis is carried out in ABAQUS for traditional and new buffer isolation solutions. Then, the effect of high overload on their optical response is evaluated with the ZEMAX software. Finally, a high overload impact test is performed. It can be seen that for the 70,000 g impact acceleration, the new buffer isolation method can reduce the impact load by about 10 times. Furthermore, the beam shaping quality of receiving system is comparable to that of the original beam without high overload.
