The dependence of ribbons time drift of a spatial optical modulator on the driving voltage is analyzed. It was assumed that mechanical stress, which follows from non 180° domain wall movement, results in asymmetrical positioning of coercive and rela

The peculiarities of 1D projection displays using spatial light modulators (SLM1) are considered. The conditions for high contrast images in SLM are investigated. It is shown that an amplitude imbalance between the light reflected from the passive an
