Abstract

Nowadays many large aperture optical components are widely used in the high-tech area, how to test them become more and more important. Here describes a new method to test the large aperture optical components using the small aperture interferometer, deduce how to get the aperture number and the concrete process of the stitching parameter in a systematic way, finally get the best plan to choose the sub-aperture of the square and circular optical plane. To specify the stability of the method we operate an experiment, the result shows that the stitching accuracy can reach λ/10, it meet the need of the inertia constraint fusion etc, that is good enough to be used in the high-tech area.
