Laser Multi-Spectral Polarimetric Diffuse-Scatter Imaging

Laser multi-spectral polarimetric diffuse-scatter imaging is a technique that maps the spectral, polarimetric, and diffused scattering response functions of an object, rather than the scattered light intensity. Application of the technique to a number of targets, which included controlled objects with known optical properties and unknown objects including drug pills and insect wing, suggests its capability to discriminate and interpret features that are ambiguous or not evident with conventional Fourier optics images. Theoretical study also indicates its potential for large-angle diffuse scatter scanning microscopy that collects image information not available for on-axis scanning.
