ABSTRACT:
The disclosed heterodyne measurement apparatus utilizes a single coherent light source to simultaneously measure the location of a number of points on a surface. The coherent light is split into two parts by a Bragg Cell. One part, after being spatially split into a plurality of beams by a second Bragg Cell, fed to a plurality of reflectors on the surface, and recombined by the second Bragg Cell, is heterodyned with the second part. The heterodyned signal is fed to a photodetector and further processed to produce a signal representative to the distance to the points of interest on the surface.
