Abstract

In this work we applied optimal filtering for reduction of detection limit in a signal registered with the diode laser spectrometer. The noise of the spectrometer operating in pulsed mode was investigated and sources of noise were analyzed. The noise shows correlation within a single laser pulse and among different pulses. This fact of noise correlation was the reason of application of optimal filtering.
