Abstract
Generally, in conventional optical interferometry, generation of speckles has been regarded as a noise and an error source degrading the reliability of the measurement because the phase is determined in a completely deterministic way. Recently, we have proposed and developed a new interferometric technique called statistical interferometry and demonstrated its validity1,2). In the method, completely random wave fronts, i.e. speckle fields, play a role of the standard of phase in a statistical sense. In the present study, we have applied the statistical interferometry to the measurement of thermal expansion of an object.
