Method and Apparatus for High Resolution Spectroscopy

Abstract

A method and a matching system for providing high resolution spectroscopy measurements. Input light beam is spread, forming two dimensional array of beams. These beams are further intercepted by two dimensional detecting means. A corresponding electronic system interprets the power collected by each detecting element subsequently producing spectral data.
