Abstract

PURPOSE:To effectively eliminate the light emission from an atomizing section so as to improve the mearuing accuracy by modulating the light from its source with a preset frequency, which is larger than the light emitting one of the atomizing seciton, and by providing a band-pass filter having the same center frequency.
