Abstract
A simple method is described for obtaining the expansion coefficient of specularly reflecting objects. The method photographically records the interference pattern of laser light reflected from the object. The moire beat between interference patterns recorded at two temperatures gives the expansion coefficient. When limited to smooth round objects, the technique is insensitive to rigid body motions of the specimens.Keywords
