摘要
Compared with the pyramid wavefront sensor, double-roof wavefront sensor (DRWFS) has great advantages in reducing the difficulty of manufacturing. In this paper, the geometric optical structure of a double-roof prisms is analyzed. Based on Fourier optical analysis, the principle of wavefront detection of DRWFS is theoretically derived in frequency domain. By simulation, the reconstructed accuracy of DRWFS for small single-order Zernike aberration and large multi-order Zernike aberration is calculated and compared. The calculation shows DRWFS can reconstruct aberrations effectively.
