Title: Analysis of doppler induced optical feedback interferometry for point-of-use refractometry
Abstract: The paper presents a flow-refractometry based on the Doppler Effect. The presented work provides an in-depth analysis of the design and principle of the Doppler based refractometry. The simulative study is performed by solving the modified Lang-Kobayashi model numerically, and the results of the study are verified. The paper also presents a modification in the design to enhance the measuring capability of the Doppler based refractometry. The modification in the design improves the measuring range of the refractometry by increasing the amount of reflection available for the interference. The proposed method can measure a wide range of the refractive index. The proposed design of the refractometry reports a standard deviation of the order of 10−5 for the refractive index ranging from 1.3 to 2.5. The design and precision of the refractometer also qualify the requirement of the point-of-care devices based on the refractive index variations developed for COVID-19 diagnosis.
