Abstract:

An optical imaging system is described that simultaneously measures the wavelength dependence and polarization state dependence of light reflected from any surface. Potential applications of this technology include identifying man made objects from natural backgrounds, land cover classification, and a myriad of agricultural problems such as ground moisture measurements, estimation of crop health, etc. Polarization effects are quantified through the use of Stokes parameters. Both spatial and wavelength dependent data are collected simultaneously through the use of a phase only computer generated hologram as a diffraction grating. Image reconstruction is achieved through an inversion procedure called computed tomography.
