ABSTRACT:
An apparatus for a liquid crystal image projection system having a liquid crystal cell, including optical apparatus for inducing a uniform texture of scattering centers in a liquid crystal cell by impinging a pulse of optical energy on the liquid crystal cell, thereby the optical energy is absorbed and converted to thermal energy heating the liquid cyrstal to a second temperture, the end of the pulse bringing about a cooling which causes the liquid crystal centers within the liquid crystal cells to scatter in a uniform texture.
