Paper Abstract

The paper reviews our recent studies on spatio-temporal heterodyne interferometry. The technique employs both spatial and temporal carrier frequencies to make highly efficient use of the limited spatio-temporal frequency bandwidth available for the fringe detection system. A new concept of a virtual wavefront is introduced, and the generation and detection of the virtual wavefront by a space-time degenerate scan-synchronized wavelength-shift interferometer are proposed and demonstrated by experiments.
