Characterization of a Low-Cost Optical Flow Sensor When Using an External Laser as a Direct Illumination Source
In this paper, a low cost optical flow sensor is combined with an external laser device to measure surface displacements and mechanical oscillations. The measurement system is based on applying coherent light to a diffuser surface and using an optical flow sensor to analyze the reflected and transfe...
