Abstract
A white-light speckle optometer is proposed for accommodation studies. It consists essentially of a coarse reflecting diffuser illuminated by a white-light point source. The source rotates on a disk, thus producing a rotating scattered field from the diffuser. This in turn produces speckle motion for the defocused eye and zero motion for the focused eye. The optometer competes quite well with the laser speckle optometer.
