Abstract

Optical antenna is an afocal telescope system which used to transmit or receive optical signals in free-space laser communication systems. In designing a high performance optical antenna, the challenging tasks including achieving of very compact and light weight optical configuration, appropriate exit pupil distance, high transmission efficiency, and wide temperature working range. The formulae of Gaussian parameters between the objective and eyepiece are derived by using the ideal imaging process. A first-order optics analysis of the optical antenna is given, which allows optics engineers to pre-define a suitable optical layout before performing design optimization and analysis. Design examples of off-axis reflective optical system are presented.
