Wide-angle catadioptric lens with a rectilinear projection scheme

Appl Opt. 2006 Dec 1;45(34):8659-73. doi: 10.1364/ao.45.008659.

Abstract

A catadioptric wide-angle lens having a rectilinear projection scheme has been developed with a view to possible applications in the security-surveillance area. The lens has been designed for a miniature camera with a video graphics array-grade 1/3 in. color CCD sensor. The field of view of the lens is over 151 degrees , and still distortion is under 1%. Furthermore, the modulation transfer function is better than 0.3 at 70 line pairs/mm over the whole active area of the image sensor.
