Optically transmissive and reflective objects may have varying surface profiles, which
translate to arbitrary phase profiles for light either transmitted through or reflected from the …

摘要光学非球面在先进光学系统中有着广泛的应用, 其面形和参数的高精度测量是光学非球面
加工和装调的基础. 从面形误差和参数误差两类被测量的角度, 阐述了各种典型的干涉测量方法 …

Non-null tests are more versatile than null tests and could give fast, generic tests with
sufficient performance. The non-null testing methods are able to measure aspheric surfaces …

We report on the effect of retrace error during measurement of freeform optics using a
commercial coherence scanning interferometer (CSI), and its in-built stitching capabilities. It …

光学自由曲面因其表面自由度较大, 可以针对性地提供或矫正不同的轴上或轴外像差,
同时满足现代光学系统高性能, 轻量化和微型化的要求, 逐渐成为现代光学工程领域的热点 …

We report a method of using a liquid-crystal spatial light modulator (LC-SLM) as
reconfigurable multi-level interferogram-type computer generated holograms (ICGHs) to …

With the rapid development of modern manufacturing processes, ultra-precision structured
freeform surfaces are being widely explored for components with special surface …

The primary problem of conventional wavefront interferometers is limited dynamic range.
Unknown free-form surface figure error with large amplitude or slope is not measurable for …

A null lens moving back and forth relative to a point source can generate variable spherical
aberration for flexible test of aspheres. Different from the previous methods, variable …
