摘要
本文提出一种具有高分辨率的新型光学系统——自选择光学,它能协调考虑大气和望远镜系统的作用,自动实时地选择出理想的像的形成过程并加以利用.该系统比以往的主动光学以及自适应光学更具可行性;对望远镜面形精度的降低,提供了一种用红外镜面实现光学波段的自选择光学的观测之可能性.本文主要给出了自选择光学的系统效率.
The author endeavours to propose the reasons for the introduction of a new optical system-selective optics, to which real time selection and utilization over the ideal image formation is employed in optimize system performance in the presence of random disturbances. Despite of its low efficiency, the selective optics have some advantages: ·Availability ·Low cost ·Possible use of moderate precision components such as infrared mirrors ·Probable combination with adaptive optics by which the systematic errors (low-order errors) due to misalignment, decentering, or defocus can be corrected.
