Abstract
The optical surface deviation of the lens can directly affect the quality of the optical system. In order to improve efficiency and accuracy of optical surface detection, an on-line testing system for optical surface based on polarizing coherent technology is designed and developed. No lying walls are required for the lens. In other words, they can be checked out the deviation of radius of curvature and astigmatism online. Based on the Tyman-Green interference light path, the system joins the polarization interference measuring technology. This paper makes a theoretical derivation and ZEMAX software simulation on the light path, sets up the experimental light path of the system. At last, comparison on image of Tyman-Green interference technology, the contrast of interference fringe image is improved significantly after joining polarizing coherent technology. And background noise and stray light are significantly reduced. It provides the foundation for improving the precision of image processing.
