Abstract
A new noncontact detection method has been proposed in order to solve the problem that the accuracy of complex freeform surface detection is not high enough and the Poor adaptability, which using optical probe with standard reflective spherical shell lens of Tyman-Green interferometer. The probe is made up by laser beam, convergent lens, diaphragm and standard reflective spherical shell lens. The laser beam is converged to a guass focus, which is overlapped with the centre of the inner surface of translucent spherical shell. Ideally, the beam is converged onto the surface of the lens and reflected to the inner surface of the spherical shell, then returned to the original path. Wave front information, when the focal point is located at a different position of the detected surface including defocus, over-focus, and ideal focus, was obtained by ZEMAX. The longitudinal positioning accuracy of the surface is discussed and proved to 100nm, which is carried out by preliminary analysis of wavefront information.
