Abstract

In this study, we propose a sensor system to improve the performance of distance measurement using multiple paralleled position sensitive detector (PSD) sensors. The PSD sensor uses a light emitted diode (LED) to illuminate an object and measures the distance to the object by the position on the PSD of the gathered light from the object. The proposed sensor system uses two symmetrically paralleled PSD sensors to increase the measuring distance extent and accuracy. Experimental results showed that the proposed PSD sensor system has an enlarged measuring extent, and has a measuring accuracy better than or equal to the conventional one.
