摘要

通常离轴三反射镜系统的反射镜孔径大，表面形状差异大，由于测试设备动态范围的限制，很难使用一套零补偿器对离轴三反射镜系统中的所有非球面反射镜进行测试。本文提出了一种结合折射变焦透镜组和空间光调制器(SLM)作为零补偿器的曲面形状测试方法，用于测试一个离轴三镜系统的所有非球面。通过对一个离轴三反射镜系统中三个非球面反射镜的零测试过程进行仿真验证，并考虑了加工误差和对准误差。仿真结果表明，主镜残余波像差在0.1λ RMS以内的概率为50%，副镜为40%，三镜为80%。

Optical design of a null test for off-axis three-mirror system based on refractive-diffractive zoom hybrid compensator

In general, the reflectors of off-axis three-mirror system have large apertures and large differences in surface shape, which means it is difficult to use one set of null compensators to test all the aspheric mirrors in the off-axis three-mirror system because of the limitation of the dynamic range of the testing equipment. In this paper, we propose a surface shape test method that combines a refractive-zoom lens group and a Spatial Light Modulator (SLM) as a null compensator to test all the aspheric surfaces of one off-axis three-mirror system. The proposed method is verified by simulating the null test process of three aspheric mirrors of one off-axis three-mirror system, with the consideration of the fabrication and alignment errors. Simulation results show that the probability that residual wave aberration is within 0.1λ RMS is 50% for the primary mirror and 40% for the secondary mirror and 80% for the tertiary mirror.

期刊介绍： The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope. Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. General topics covered include: • Optical and photonic materials (inc. metamaterials) • Plasmonics and nanophotonics • Quantum optics (inc. quantum information) • Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers) • Coherence, propagation, polarization and manipulation (classical optics) • Scattering and holography (diffractive optics) • Optical fibres and optical communications (inc. integrated optics, amplifiers) • Vision science and applications • Medical and biomedical optics • Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy) • Imaging and Image processing
