英文摘要	Wavefront sensing in monochromatic light has 2π ambiguity. To resolve this ambiguity, the wavefront sensing is performed in two wavelengths. A new algorithm is proposed to find the correct phase, and the algorithm is verified by simulation. Using the algorithm, the capture range of a wavefront sensor can be extended from on the order of λ/2 in a segmented mirror piston error to several waves. Lastly, a co-phasing experiment system of the segmented mirror is built to verify the algorithm. In the experiment, one wavelength is 0.65 μm, and the other is 0.636 μm. After the co-phasing fine tuning of the segmented mirror, the piston error of the segmented mirror is better than λ/20. © 2016 Optical Society of America.
