Abstract

This paper demonstrates design and development of an open-source platform-based reflection spectroscopy readout system for guided mode resonance (GMR) sensing applications. The GMR dimensions, reflection grating period, imaging system and components orientations are optimized to enhance the angular resolution while sustaining resonance excitation within the visible range. To achieve the needed arrangement of the multiple components, 3D printing is utilized to build the mechanical mounting. The reflection spectra are extracted from the webcam images and processed using a software written on raspberry-pi computational unit. This ensures the compactness and portability of the system. The system performance of the transducer is tested by measuring the changes in the refractive index of the environment at the GMR chip interface.
