  • Cooling system for spatial light modulating devices
    Patent number: 10873730
    Abstract: A cooling system for controlling the temperature of a light valve of a projection system, the light valve being illuminated by a light source, the cooling system including a first sensor for measuring a first temperature of a first part of the light valve, at least one active heating and/or cooling device to transfer heat between the light valve and a heat source and/or sink, a controller for controlling the temperature of the light valve with the at least one active heating and/or cooling device according to the first temperature with respect to a reference temperature. The cooling system further includes a sensor for determining the amount of light absorbed by the light valve, and where the controller is further configured to control the active heating and/or cooling device based on the amount of light absorbed by the light valve.
