ELECTRO-OPTIC SPATIAL MODULATOR FOR HIGH ENERGY DENSITY

摘要

The present invention provides an imaging assembly comprising: (a) a modulator crystal (12) comprising a first surface (11) and a second surface substantially opposite to the first surface (11), wherein the first surface (11) comprises an active area (26); and (b) a heating element (20) for heating the modulator crystal (12) to a temperature within a predetermined temperature range, wherein the heating element (20) is positioned under the modulator crystal and comprises a first surface (21), wherein the heating element (20) first surface (21) faces the modulator crystal (12) second surface and covers a portion of the modulator crystal second surface such that the active area (26) of the first surface (11) of the modulator crystal (12) has a homogeneous temperature distribution. The present invention also provides a method for heating a modulator crystal in an imaging assembly.
