Quasi-random Scanning of a Digitally Controlled Spectrometry

Koga, Ryuji
Sano, Hiroya
Abstract
A quasi-random method for spectral scanning is proposed to reduce an alias response to a quick change in the source abundance. A direct application is made for an atmospheric methane monitoring with a current-tunable diode laser. Only barrel shift methods are examined being found further vulnerable to drifting etalon fringes.
