Abstract

Some problems about registration of low intensity spectral lines by using photon counting method are discussed. Application of the MC6840 Programmable Timer in automated data acquisition systems is described. A microprocessor based automated system for registration of spectral lines with piezoelectrically scanned Fabry-Perot interferometer is described. Algorithms are shown.
