模拟研究结果表明，相位差法可以较准确的恢复出波前相位，并且最优化的离焦波面差为一个波长。
Simulation results show phase-diversity method can accurately retrieve the wavefront and defocusing of one wavelength is optimal.
由于相位差异法的运算量巨大，在PC平台上的软件实现难以实时、快速的恢复图像。
Due to the great computations, it is difficult to increase the speed of PD to satisfy real time application on PC platform.
