Embodiment Construction
[0046] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0047] Such as figure 1 As shown, a radial shear interference wavefront detection device based on micro-optical devices includes a polarization direction modulator 1, a polarization ring direction shear system (CRSS), and a microwave plate array 7 and an analyzer 8. Micro phase modulation array MPA, and photodetector 9 etc. are composed.
[0048] After the distorted beam enters the radial shear interference wavefront detection device based on micro-optical devices, it first passes through the polarization direction modulator 1, whose main function is to select or change the polarization state of the incident light to form linearly polarized light with a specific polarization direction. The incident light beam is converted into linearly polarized light with a specific polarization direction after passing through the polarization modulator 1. ...
