ABSTRACT:
A holographic spinner reconstructs a light spot to rapidly scan a narrow line on a suitable "write" surface to generate an image. The geometry of the holographic spinner with respect to the holographic reconstruction light beam is such that the position of the regenerated light spot is insensitive to mechanical wobble which might be present in the spinner mechanism.
