摘要：
A Hartmann-Shack wavefront sensor is designed for adaptive optics confocal scanning laser ophthalmoscopy. The Hartmann-Shack wavefront sensor designed consists of a lenslet array with square configuration, sub-aperture size 0.2mmx0.2mm, focal length 5mm and a CCD camera with pixel size 3.75 mu mx3.75 mu m.The dynamic range and measurement accuracy of the HSWFS are simulated through the software MATLAB. The result of simulation indicates that focus dynamic range +/- 14 lambda (lambda=635nm), wavefront measurement accuracy reach RMS lambda/100, all these indicators reached the requirements of the system. Finally, experiments of calibration by spherical wavefront were done on these indicators.
