Perceiving a 3D moving target is important for automated machines including robots in a factory. Although stereo-vision or ultrasonic ranging is often employed for the purpose, the former requires high-cost systems, and the later sufersfrom low-resolution. In this paper, we propose a PSD sensor array to acquire the 3D profile of an object conveyed byconfigured in a 3×3 array above the belt, and fired in a sequence so that cross-talk can be avoided. Time gaps amongsensor readings are compensated to get a result that is obtainable when sensors' measurements are made simultaneouslyalong a sensing line. The system designed is tested with various objects in experiments.
