Abstract
An image modulating system including layers such as a formatter plate (PCB), an electrical connector plate called an interposer, a back cooling block, a front cooling frame and a reflective spatial light modulator. A cooling heat transfer channel is provided to transfer heat between the front cooling frame of the light valve and the back cooling block of the reflective spatial light modulator so as to reduce the thermal gradient between the front and back of the reflective spatial light modulator. The cooling heat transfer channel passes through any intervening layers such as the formatter plate (PCB), and/or the electrical connector plate called the interposer. The cooling heat transfer channel is preferably formed of a heat pipe or a circulating cooling medium.
