Abstract

In this paper, a low-light-level panoramic imaging system was designed based on the domestic second generation semi low-light-level tube. It has a waveband of 0.4 μm to 0.9μm, an effective focal length of 2.43mm, a working F-number of 1.5, and a field of view 30°～100°. Simulation results show that in the entire field of view, the f-θ distortion is less than 6%. The value of the MTF at 24 lp/mm is greater than 0.3. A mechanical structure supporting was designed. The stray light of this imaging system with its mechanical structure supporting was theoretical analyzed by using the software ZEMAX. A actual measurement was also carried out by a France stray light measuring instrument REFLET-180. The actual measurement results match with the theoretical results well in the simulation accuracy that verify the correctness of theoretical analysis and prove the feasibility of system design.
