Abstract: Based on the analysis of the luminous characteristics of typical lasers and optical properties of cylindrical lenses, a novel optical system for laser panoramic fuse, which uses two sets of cylindrical lenses with orthogonal sagittal planes to improve the scattering angle of laser beam and uses four sectors to realize the panoramic function, is proposed in this paper. Since the distribution uniformity of the light energy of the system is satisfactory on the circle of 0.5～10m radius and the beam path of the system offers an advantage of invertibility, it can be used in the fuse of the missile with the feature of WFOV emission and reception. The system is comparable to its counterpart abroad. The system is compact in structure and easy to be fabricated. The demonstration in the test range proves the new optical system is feasible and practical. The reflective optical system available will be replaced by this system in the future.
