Hartmann-Shack sensor as a component in active optical system to improve the depth resolution of the laser tomographic scanner

This paper presents the measurement of the wave aberrations of human eyes with a Hartmann-Shack Sensor (HSS), used in a system for active optical depth resolution improvement of the Laser Tomographic Scanner(LTS). A least-squares algorithm of modal wavefront estimation from the tested derivatives is described. The noise propagation of this algorithm is examined. And the experimental results of tested living eyes are presented.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.
