Abstract

A new improved design method of the panoramic annular lens (PAL) with aspheric surfaces is introduced. The structure is not only helpful to enlarge the field of view (FOV) of the system, but also help to make a horizontal symmetric field of view. The field of view reaches （-30°—+30°）x 360 and was distortion controlled to reduce blind zone in the center. The field of view and distortion of PAL was investigated theoretically and method of aspheric surface design was also discussed. An aspheric PAL and its relay lens group were designed. The total length was 20.4mm, and the focal length was 0.3mm. To get bright and clear image, the aperture of the system was set to f/2.88, and the diameter was 16.6mm. The spectral range was from 0.486~0.656um. The relay lens group was consisted of 8 pieces of lenses, with a back focal length (BFL) of 2mm. MTF below 70 lp/mm of the system is above 0.5. The result shows that the aberrations are corrected well.
