Abstract

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 0.2mm×0.2mm , focal length 5mm and a CCD camera with pixel size 3.75μm×3.75μm.Thedynamic range and measurement accuracy of the HSWFS are simulated through the software MATLAB. Theresult of simulation indicates that focus dynamic range±14λ (λ=635nm), wavefront measurement accuracyreach RMS λ/100, all these indicators reached the requirements of the system. Finally, experimentsofcalibration by spherical wavefront were done on these indicators.
