“…The objective function and the partial derivative of PR objective function with respect to n α respectively is formula (3) and formula (4) With the objective function (3) and its impact on the Zernike coefficient derivative (4), we can use the mathematical optimization algorithm to solve various Zernike wavefront coefficient values, here we use LBFGS algorithm that the phase diversity (PD) [24][25][26][27][28][29][30] experiment has been able to solve.…”

In order to verify the estimated wavefront ability of the phase retrieval wavefront sensor (PRWS), a measured spherical mirror of experiment platform was set up with the method of PRWS. PRWS technology is based on the focal plane image information wavefront solver in the focal plane wavefront measured technology, whose principle is sampling a number of the given defocus images; get the wavefront phase information by solving the optical system wavefront with Fourier optical diffractive theory and mathematics optimization. In order to validate the veracity of PRWS, both the PRWS measurement results and ZYGO interferometer measurement results were compared; experimental results demonstrate that agreement is obtained among the errors distribution, PV value and RMS value of ZYGO interferometer, so PRWS technology can effectively estimate the aberrations of spherical mirror.

We propose a holographic adaptive optics system based on holographic wavefront sensor and 21-element deformable mirror, and analyze the wavefront correction ability of the system in this paper. The principle of holographic wavefront sensor is described, and its numerical model is provided by fast Fourier transform algorithm in the thin hologram approximation. Then, the wavefront correction ability of 21-element deformable mirror is analyzed with its numerical model. Finally, the aberration compensation of the system is simulated and an experimental device is set up to verify the feasibility of the proposed adaptive optics system.
