Title: TELEPHOTO ARRAY OPTICAL SYSTEM
Abstract:
This telephoto array lens system has: one afocal optical system; and an array optical system disposed in parallel and configured from an image formation optical system comprising a plurality of layers. When a parallel light beam enters the afocal optical system, the afocal optical system causes the exit of a parallel light beam in a manner such that the light beam width of the exiting light beam from the afocal optical system is smaller than the light beam width of the entering light beam to the afocal optical system, and the exit angle formed by the exiting light beam from the afocal optical system with respect to the optical axis is greater than the entrance angle of the entering light beam to the afocal optical system with respect to the optical axis. The image formation optical system comprising a plurality of layers forms a plurality of optical images by causing exiting light beams that have passed in common through the one afocal optical system to individually form images.
