An interferometer has been developed which provides repetitive spatial profiles of phase objects in the ir using a single detector channel. By combining Bragg cell heterodyne interferometry with a high speed (0.5 million rpm) turbine driven rotating mirror scanner, the system scans a 5-cm field with a 2-mm resolution in 200 nsec. Operating in a double pass mode at 3.4 ..mu..m, the phase accuracy is better than 0.1 fringe. The concept is applicable over a wide range in wavelength, scan format, and resolution.
