Abstract
Intracavity absorption spectroscopy is a strikingly sensitive technique that has been integrated with a two-wavelength setup to develop a sensor for human breath. Various factors are considered in such a scenario, out of which Relative Intensity Noise (RIN) has been exploited as an important parameter to characterize and calibrate the said setup. During the performance of an electrical based assessment arrangement which has been developed in the laboratory as an alternative to the expensive Agilent setup, the optical amplifier plays a pivotal role in its development and operation, along with other components and their significance. Therefore, the investigation and technical analysis of the amplifier in the system has been explored in detail. The algorithm developed for the automatic measurements of the system has been effectively deployed in terms of the laser's performance. With this in perspective, a frequency dependent calibration has been pursued in depth with this scheme which enhances the sensor's efficiency in terms of its sensitivity. In this way, our investigation helps us in a better understanding and implementation perspective of the proposed system, as the outcomes of our analysis adds to the precision and accuracy of the entire system.
