Application of High-Photoelasticity Polyurethane to Tactile Sensor for Robot Hands. [PDF]
Polymers (Basel), 2022 We developed a tactile sensor for robot hands that can measure normal force (FZ) and tangential forces (FX and FY) using photoelasticity. This tactile sensor has three photodiodes and three light-emitting diode (LED) white light sources.

Application of principal component analysis in phase-shifting photoelasticity [PDF]
Optics Express, 2016 Principal component analysis phase shifting (PCA) is a useful tool for fringe pattern demodulation in phase shifting interferometry. The PCA has no restrictions on background intensity or fringe modulation, and it is a self-calibrating phase sampling ...
