摘要
An apparatus rapidly reads out wavefront errors of an input wavefront and includes a holographic optical element (HOE), a position readout detector and a readout device. The HOE receives the input wavefront and includes a hologram of a particular wavefront recorded with reference waves, each defining a particular aberration coefficient. The position readout detector includes a plurality of position sensing devices (PSDs) receiving an optical output of the HOE, each PSD sensing the occurrence and magnitude in the input wavefront of any of the particular aberrations defined by the reference waves recorded to the holographic optical element with the particular wavefront. The readout device provides a readout value of each PSD upon application of the input wavefront to the holograph optical element, each readout value representing in the input wavefront the presence and magnitude of any of the particular aberrations defined by the reference waves.
