Abstract

The paper is to introduce the principles of vector optical heterodyning principally enable for new aerospace sensor systems. This approach comes form a new adjoining coherent method of elastic light scattering, which was earlier experimentally provided for the specific small-size experiments of dynamics light scattering. The theory of vector optical heterodyning for remote sizing and velocimetry is presented. The method is available to advance within the technique for coherent signal processing, which appears to be available by beating several scattered vector waves within a square-low photo-detector by their registration. While the classical passive methods of optical beating deals with the problem to study a scalar optical signal that is due to elastic scattering with a Doppler shift and a single narrow-band laser beam, the new method deals with two vector waves simultaneously undergo scattering by a target. In case one of the vector waves has strong periodical modulation of direction of polarization. Coherent Light Beating Scattering occurs, which units elastic Light Scattering and Coherent non-linear Beating within the square-low photo-detector. As a result, the vector optical signal provides the information about both size and velocity of a remote scattering object, which is not available for well-known Doppler methods with scalar optical heterodyning.
