Abstract: This paper demonstrates a highly sensitive digital readout method for angular displacement measurement using a two-dimensional transmission diffraction grating and a smartphone CMOS camera.

Capacitive displacement sensors turn tiny gaps into actionable signals. By measuring changes in capacitance as target moves, these devices deliver precise, non-contact readings of position and motion.

Abstract: As bridges deteriorate over time, the need for effective bridge structural health monitoring (SHM) becomes increasingly critical. Dynamic displacement serves as a key indicator for ...
