COMPACT FOUR-MIRROR ANASTIGMAT TELESCOPE
Abstract:
An optical system (20) comprises a three-mirror anastigmat (22) including a primary mirror (24), a secondary mirror (26), and a tertiary mirror (28) positioned to reflect a beam path (30). An intermediate image (32) is formed on the beam path (30) at an intermediate-image location between the secondary mirror (26) and the tertiary mirror (28). A negative-optical-power field mirror (34) is positioned in the beam path (30) at a field-mirror location subsequent to the intermediate-image location along the beam path (30). The field mirror (34) reflects the intermediate image (32) to the tertiary mirror (28).
Abstract(Chinese):

光学系统（20）包括三镜式反射镜（22），其包括主镜（24），副镜（26）和定位成反射光束路径（30）的第三反射镜（28）。 在副镜（26）和第三镜（28）之间的中间图像位置处，在光束路径（30）上形成中间图像（32）。 负光学场反射镜（34）在沿着光束路径（30）的中间图像位置之后的场镜反射镜位置处定位在光束路径（30）中。 场反射镜（34）将中间图像（32）反射到第三反射镜（28）。
