Abstract: Incremental optical encoders are widely used as photoelectric sensing components in direct current motor servo systems, but their inherent susceptibility to optical interference ultimately ...

Abstract: This paper reports on a proof-of-concept SPAD-based (Single Photon Avalanche Diode) optical encoder. The work aims at demonstrating the advantages of SPADs over photodiodes, which are ...

This project implements a real-time optical heart rate monitoring system using a transmissive photoplethysmography (PPG) sensor integrated with an Arduino and a LabVIEW signal-processing pipeline. The ...
