摘要
A holographic scanning system includes a reflective type holographic spinner having a plurality of diffraction gratings on its surface. A reconstruction wavefront incident on a non-grating surface of the spinner is reflected into a corrective optical element which displaces and redirects the wavefront so that it is incident at the grating at an angle corrected for the effects of spinner wobble.
