Abstract

Progressive addition lens (PAL) is a kind of lens with which optical power gradually increases from top to bottom. Hartmann-Shack Sensor (HSS) is a kind of measuring instrument for wavefront aberration. Considering that the exit pupil of the measured optical system and the entrance pupil of HSS in general are different, we must bring them together and make them with same size in order to make full use of the aperture of HSS, and to meet the requirements that all the emergent light of the measured optical system enter into the sensor. In this paper, 4F system was proposed to realize the cohesion between the two pupils, combined with HSS to measure the diopter and aberration distribution of the PAL. The principle of the system was expounded in the paper. Also the conversion relation between the detection result according to HSS and the actual situation of the PAL was researched. Precision measurements of diopter and aberration of the PAL based on HSS was achieved ultimately.
