dc.descriptionAn acousto-optic cell was used to reduce the speckle noise that reduces the quality of Hartmann-Shack and other wave-front sensors measuring ocular aberrations. In the method presented here, a laser beam traverses an acousto-optic cell, interacting with standing acoustic waves. Speckle reduction takes place as the incoming beam is diffractively spread across the cornea. The increased size and the wider angular spread of the incoming beam average out the speckles, producing a more uniform response of the wave-front sensor.
