Abstract:

A technique for background suppression for use in Dual Beam Interferometers and other imaging systems is described. Background suppression is achieved by using pairs of optical systems whose modulation transfer functions match at low spatial frequencies but not at the higher frequencies which characterize a target. Various pairs of systems are discussed, and signal-to-RMS-clutter-leakages are calculated. Author
