A frequency-shifted local oscillator beam was produced by a rotating radial grating in an infrared heterodyne detector operating with a CO2 laser. Reduction in mixing efficiency due to beam distortion on diffraction from the radial grating was predic

A new technique is described that is capable of sensing surface roughness of moving materials. The method is based on analysis of the intensity fluctuations of laser light backscattered at an angle from the surface. The optical correlation length sup
