OPTICAL SYSTEMS INCLUDING LENS ASSEMBLIES AND METHODS OF IMAGING FIELDS OF VIEW USING SUCH OPTICAL SYSTEMS

摘要

Optical systems including lens assemblies and methods of imaging fields of view using such optical systems are disclosed. An optical system for imaging a two dimensional field includes a first lens assembly, a first scanning mirror, a second lens assembly, and a two dimensional image sensor. The first lens assembly has a first transform function whose output is within 0.1% of ∫1*(C1 * θ1 + (1-C1)*sin(θ1)) for any ray of light that traverses the first lens assembly from a center of an entrance pupil of the first lens assembly at an angle θ1 relative to an optical axis of the first lens assembly, ∫1 is a focal length of the first lens assembly, and -0.5 c1 2.
