Digital Spectra Synthesis,

Authors: Wun C. Chiou; ARMY AEROMEDICAL RESEARCH LAB FORT RUCKER ALA

Abstract:

Digital spectra synthesis is a digitizing technique for spectra synthesis which offers certain preferential and desirable features of the relative energy spectral distribution by compositing two or more known electromagnetic radiation spectra. One can derive and thus predict the chormaticity properties of any given new spectrum. Several experimental examples will be given. The CIE chromaticity characteristics of several resultant spectra will be derived and analyzed. The main component for the digitizing processes is the Tektronix Digital Processing Oscilloscope - Rapid Scan Spectrometer (DPO - RSS) with an automatic data processing and acquisition unit with PDP 11/05 minicomputer. The operation of this sytem will be discusssed in detail. Several entrance components including the double and the triple swan-neck fiber optics are being used in this experiment. (Author)
