Demonstration of a Low-Cost and Portable Optical Cavity-Based Sensor through Refractive Index Measurements

An optical cavity-based sensor using a differential detection method has been proposed for point-of-care diagnostics. We developed a low-cost and portable optical cavity-based sensor system using a 3D printer and off-the-shelf optical components. In this paper, we demonstrate the sensing capability...
