Abstract
A method for reconstructing a surface of an object includes the steps as follows. A light beam is modulated by a spatial light modulator (SLM) and is projected to form a pattern, wherein the pattern has a transmittance distribution in a cosine distribution such that the pattern is formed to become a fringe pattern with a periodic change. A first impulse and a second impulse present within a first period and a second period of the cosine distribution, wherein a position where the first impulse occurs within the first period and a position where the second impulse occurs within the second period are different. The light beam is guided to an object so as to form a scan pattern on the object. The scan pattern is read. According to the scan pattern, a surface profile of the object is calculated.
