Abstract

PURPOSE:To eliminate measurement errors by making flickering frequencies of atomic line source to integer times of the flickering frequencies of a continuous light source, separating the detecting signals of both lights with their frequency difference and making negative feedback of the detecting output of the continuous light to the detector thereby making the detection output constant.
