Wavefront sensing is a crucial part of adaptive optics technology. The pyramid sensor (PS) has the advantage of higher sensibility than other classical wavefront sensors. PS is capable of detecting differential piston between sub-apertures of interferometer or elements of segment mirror. On the basis of analyzing the pyramid sensor principle, a software simulation design including algorithm, some initial results and two conclusions about wavefront tip-tilt sensing of single-aperture telescope and differential piston sensing of double-aperture interferometer are discussed respectively. The next research scheme is also introduced briefly.
