High Gain Infrared Collector and Data Node

An infrared collector employs a concentrator formed of a plurality of spatially related gradient-indexed (GRIN) lenses and a photo detector interconnected by optical fibers. Since the GRIN lenses are arranged on a hemispherical shell the concentrator is relatively insensitive to the direction of the incoming infrared radiation. Optical fibers ...

Sub-monolayer detection with surface selective vibrational spectroscopy

This invention describes a new system and method for performing surface-selective spectroscopic detection with high sensitivity and low detection limits particularly in the visible and fingerprint mid-infrared spectral regions. The method offers a substantial improvement, 10-fold or more, over existing techniques. This invention has already been r...
