哈德曼-夏克传感器(Hartmann-Shack Sensor,HSS)是一种测量波前像差的仪器。提出了一种利用4F系统实现光瞳衔接,与哈德曼-夏克传感器相结合测量眼镜片的光焦度和像差分布情况的方法。阐述了该系统的工作原理,研究了哈德曼-夏克传感器所得到的检测值与实际被测光学系统的光焦度与像差之间的转换关系。考虑到人眼实际观察不同方向物体时视轴是在不断变化的,采用多光轴测量眼镜片的方法。实现了利用哈德曼-夏克传感器对于眼镜片的光焦度和像差进行精密测量。
Hartmann-Shack Sensor (HSS) is an instrument for measuring wavefront aberrations. A method of using 4F system to realize the pupil connection and measuring the optical power and the distribution of the aberration of the ophthalmic lens combined with the Hadman-Shack sensor was proposed. The working principle of this system is expounded. The relationship between the measured value obtained by the Hadman-Shack sensor and the optical power and aberration of the optical system under test is studied. Taking into account the actual human eye observation of objects in different directions when the visual axis is constantly changing, the use of multi-optical axis measurement method. It realizes the precise measurement of the optical power and aberration of the spectacle lens by using the Hadman-Shack sensor.
