Paper Abstract

The paper presents an analysis of the signal to noise ratio of distributed anti-Stokes ratio thermometry (DART) to quantify the effect of varying the gain of the avalanche photodiode (APD). An optimal gain is found based on maximizing the signal to noise ratio of the received circuit output. Good agreement between calculated and measured avalanche gain of APD is obtained.
