Abstract
A multiple depth of field optical scanner employing a mirrored spinner which is rotated about a predetermined point between the geometric center and the periphery of the spinner. The rotation point is preferably located to provide the maximum variation in depth of field that will still allow a laser to continuously illuminate the spinner as it rotates. The spinner may be additionally rotated about its geometric center, if desired.
