Abstract
An optically addressed light valve is disclosed which is cabable of being read-out at very high light intensities during the write-in cycle without need for an optical blocking layer. The system is based on the combination of a reflective photoconductor and an electro-optically active medium and exploits the characteristics of space charge limited currents in photoconductors of high optical absorption of actinic wavelengths.
