Abstract
The study of the temporal performance of a nematic liquid crystal phas e modulator with 69 phase retardance cells is presented. The change of Strehl ratio for defocus under static and dynamic conditions is discu ssed. It is observed that the rate of arbitrary phase modulation is li mited to about 1.7 Hz with this device. Finally, suggestions for impro ving the bandwidth are given. (C) 1997 Published by Elsevier Science B .V.
