Abstract

A new multiple wavelength interferometer makes use of stabilised helium-neon and argon ion lasers to measure the length of engineer's gauge blocks. The combination of television and computing techniques to analyse the resulting interferogram makes the instrument less dependent on operator skills and is able to provide data about the gauge surface.
