METHOD AND MEANS FOR GENERATING SYNTHETIC SPECTRA ALLOWING QUANTITATIVE MEASUREMENT IN NEAR INFRARED MEASURING INSTRUMENTS

摘要

A method and means for generating synthetic spectraallowing quantitative measurement utilizes dual chip (12, 14)alternatively energized IREDs with optical bandpass filter(s)(22,24) passing two optical bands which could be combinedwith curvilinear interpolation to be utilized in a low costsmall size quantitative measuring instrument.
