Abstract

The effect of laser noise on the frequency resolution of an acousto-optic FM demodulator is investigated. Formulae are developed which allow prediction of the demodulator's frequency resolution when affected by laser intensity noise. The limiting laser intensity SNR is calculated in order to determine the required laser SNR which will not degrade system performance.
