Paper Abstract

This paper describes a fiber-optic interferometer which uses two laser diodes in a modified Mach-Zender configuration for testing aspherical surfaces with phase shift technique and a possibility to implement two wavelength technique. Experimental results show that this type of interferometer is very useful for in-process control directly on a diamond turning machine, the test element still attached to the chuck.
