Abstract
A PLZT based shutter system reduces flare produced by reflective surfaces normally associated with PLZT based and other SLR shutter systems by eliminating a diffraction mirror and using highly reflective electrodes directly on the PLZT element to function both as the reflective mirror and as the electrodes to produce the E field in the PLZT element. The invention has an improved performance by reducing flare and has a reduced parts count improving its manufacturability and reliability.
