By simulating wavefront reconstruction with Zernike polynomials, the performance of the sector lens array configuration in H-S wavefront sensor was tested. Compared with square lens array configuration in H-S wavefront sensor, the sector lens array configuration in H-S wavefront sensor has better performance when the number of the array lens of the two configurations is commensurate. However, the simulating of the wavefront which was measured by the interferometer shows the two H-S wavefront sensors comparatively reconstructed the original wavefront.
