Photoelectroplating light modulator.
A two-dimensional light modulator has been developed based on the principle of photon controlled electroplating of metal onto a photoconducting semiconductor. It may be used in transmission or reflection, and forms positive or negative images. Some observed characteristics of the modulator are: 18-line pairs/mm resolution, reusability to the extent of about ten cycles, and image formation time of 0.5-5 sec. Other experimental observations are described, and device performance is analyzed in terms of semiconductor parameters.
