| 摘 要： | 在研究了SVGA1薄膜晶体管液晶显示器（TFT LCD）的位相调制特性的基础上,用它作为眼波像差的矫正器件,在用哈特曼-夏克波前传感器的眼像差测量系统中对眼波像差进行了成功的矫正.对于5.2 mm的瞳孔,矫正后人眼波像差的PV值降低了3倍多,并接近瑞利判据的像差容限.对系统的光学传递函数(MTF)的分析说明,经波像差矫正后眼的空间分辨率由17 c/deg提高到38 c/deg. |

| Abstract: | SVAG1 thin-film transistor liquid-crystal display (TFT-LCD) is successfully applied to the eyes’ wave aberration measurement system using Hartmann-Shack sensor to correct the eye’s aberrations based on the evaluation of the phase modulation properties of the device. By the correction, the peak-to-valley wave-front errors of the eye across 5.2 mm pupil are reduced by a factor of approximate three and close to the Rayleigh quarter-wave criterion. It is shown with the modulation transfer function (MTF) analysis that the ultimate spatial resolution of the eye increases from 17 c/deg to 38 c/deg by the correction. The achieved spatial resolution is not only far higher than that before the correction but also higher than the optimum spatial resolution of the normal eyes (approximate 30 c/deg). Therefore the SVAG1 TFT-LCD is a promising device in the closed-loop adaptive optics system to achieve supernormal vision and high-resolution retinal imaging. |
