Abstract

The measuring accuracy of laser optical sensors is gradually degraded over time as a result of geometrical fluctuations of the laser beam. In a previous study by the present group, a method was proposed for stabilizing the laser beam by means of a rotating optical diffuser. In the present study, the effects of the key diffuser parameters, namely the rotational speed (ω), the particle radius (r ), and the particle concentration (c), on the performance of the proposed system are evaluated both numerically and experimentally. The results confirm that given an appropriate setting of the three parameters, the proposed system reduces the variation of the image centroid position and improves the measuring accuracy of the laser optical sensor as a result.
