1. A method of controlling a temperature profile of an optical window comprising:
measuring a temperature-dependent electrical property of a thermally sensitive material included in the optical window using an embedded electromagnetic interference shield in the optical window to determine the temperature profile of the optical window, the embedded electromagnetic interference shield including a two-dimensional array of electrically conductive wires; and
based on the measurements, selectively biasing at least one wire of the two-dimensional array of electrically conductive wires to locally alter the temperature-dependent electrical property of the thermally sensitive material in at least one selected spatial region of the optical window to control the temperature profile of the optical window.
