In order to improve the wavefront sampling frequency in wavefront detection,a wavefront reconstruction method based on two element complementary mode is proposed.The method reconstructs the real part of the light field by using the far field focal light intensity obtained under binary complementary modulation mode,and then reconstructs the imaginary part of the light field through the light intensity distribution of the beam.The method avoids the use of additional modulation mode,which reduces the number of modulation modes used in the process of wavefront sampling to 2/3 of the original method,and improves the wavefront sampling frequency.The wavefront of the beam with uneven intensity distribution is reconstructed in the numerical simulation,and the tilt aberration is reconstructed by experiments,which verify the feasibility of the method.
