Paper Abstract

A simple microprocessor controlled optical sensor is proposed in this paper. It can measure two kinds of optical information: the distance between sensor and the illuminated area of the object and the inclination angles of that area. Under the control of the microprocessor, the sensor can also profile a full 360 degree(s) 3-D picture of the object by scanning a scene mechanically in vertical dimension and rotating the object to be measured in the horizontal plane. The proposed sensor has been assembled and some preliminary experiments show that it can sense the distance with a range of 10 cm in accuracy of +/- 1 mm for objects having diffuse reflectivity and the inclination angles of the area with a range of +/- 20 degree(s) with accuracy of 1.5 degree(s). A shape of a mannequin head is profiled in a full 360 degree(s) way.
