Abstract
A point laser interferometer for measuring aspheric optics is developed in this paper. The proposed laser interferometer will be used as a optical probe in optical coordinate measuring machines. The point optical probe is based on homodyne interferometry with frequency stabilized He-Ne laser to provide traceable measurements. The influences of various aspheric surface factors on the performance of point optical probe are analyzed, such as roughness, reflectivity, material, slope angle etc. A compensation method is applied in the signal processing system to reduce the influences. Experimental results show that the measurement resolution is at the nanometer level under various conditions.
