This proposal describes the design and fabrication of a new type of polarimeter which we call a single aperture-four channel optical polarimeter. it is designed to measure simultaneously the four stokes polarization parameters of an optical beam and is capable of measuring the stokes parameters of… More

This proposal describes the extension of digital spectrometry to the measurement of the anisotropic permittivities of piezoelectric materials. we show that fresnel's equations for anisotropic media, as is the case with isotropic media, also simplify for an incident angle of 45 deg. in digital… More

This proposal describes a new method for determining the refractive index and extinction coefficient of optical materials. this method is an opto-electronic method, is completely automated, extremely fast and is capable of obtaining accuracies and resolutions comparable with prism spectrometers.… More

The modern battlefield environment demands tools which can assist army commanders in making tactical decisions about a dynamic environment in a timely manner. knowledge of the terrain, such as areas of relative high ground, is a crucialfactor to many of these modern tactical decision aids. in order… More
