ABSTRACT:
The invention comprises a method and means for measuring the separation been two optical surfaces. A short-coherence-length laser pulse is projected upon two optical surfaces separated by a distance, d. The reflected, coincident beams are directed into a Michelson interferometer in which one plane mirror is replaced by a stepped mirror. The beams reflected from the two mirrors are directed onto a film where they form interference images. A formula using the number of channels, n, between successive interference fringes and the step width of the stepped mirror is used to calculate d.
