Abstract
THE PROPOSED RESEARCH IS AN INVESTIGATION OF A TECHNIQUE FOR MAKING NONCONTRACT POINT MEASUREMENTS ON DIFFUSELY SCATTERING OBJECT TARGETS AT INTERFEROMETRIC ACCURACIES. THE CONCEPT BEING CONSIDERED IS A FRINGE COUNTING OPTICAL INTERFEROMETER THAT OBSERVES THE NONSPECULAR COMPONENT OF DIFFUSELY BACKSCATTERED RADIATION FROM A SINGLE OBJECT POINTON AN UNPOLISHED SURFACE. THE KEY TO THE CONCEPT IS A NOVELAND INNOVATIVE APPROACH THAT ALLEVIATES, OR CONSIDERABLY REDUCES, THE EFFECTS OF LASER SPECKLE. THE RESULTING FRINGESTRUCTURE IS THEREFORE PRODUCED BY THE MEAN WAVEFRONT MINUS THE HIGH SPATIAL FREQUENCY SPECKLE COMPONENTS, AND THE FRINGE COUNT IS A MEASURE OF MEAN OPTICAL PATH-LENGTH TO THETARGET POINT.
