ABSTRACT:
A method for monitoring diffraction while reading a hologram includes: illuminating a holographic medium with a reference beam to generate a data beam for a hologram that has been recorded at a set diffraction efficiency with a first polarization, the reference beam having a second polarization; and measuring an offset component in an output arm of the data beam.
