HADAMARD - TRANSFORM EXHAUST - ANALYSIS SPECTROMETER

A NOVEL INSTRUMENT FOR AUTOMOBILE EXHAUST ANALYSIS BASED ON A HADAMARD-TRANSFORM SPECTROMETER IS PROPOSED, WHICH WOULD BE ABLE TO MADE ACCURATE MEASUREMENTS OF THE CONCENTRATION OF SEVERAL POLLUTANTS SIMULTANEOUSLY, WOULD BE OPERATED BY UNSKILLED PERSONNEL, AND WOULD COMPLETE A MEASUREMENT SCAN IN LESS THAN 1 SECOND. THE USE OF HTS MULTIPLEXING ALLOWS THE SIMULTANEOUS MEASUREMENT OF SEVERAL ABSORPTION/REFERENCE LINE PAIRS WITH A SINGLE AMPLIFIER/DATA-PROCESSING CHAIN. /AUTHOR/
