Abstract: A method and apparatus for protecting an optical sensor is disclosed. A fixed filter having a fixed passband for light transmission is placed in front of the optical sensor. A programmable filter having a variable passband for light transmission is placed in front of the fixed filter. A controllable voltage source controls a voltage at the programmable filter that shifts the passband of the programmable filter from a first state in which the passband of the programmable filter is substantially the same as the passband of the fixed filter and a second state in which the passband of the programmable filter is different than the passband of the fixed filter.

Abstract: A conduit is placed between a vacuum system and the open air or other gaseous environment. A laser or other excitation source is used to ionize the air on the air-side of the conduit. An axial applied electric field is used to repel positive ions from traversing the tube and reaching the region of the vacuum. Electrons are collected in the vacuum region and disposed of using a Faraday cup. The repelled ions assist in creating a counter pressure to sweep neutral atoms out of the tube and back into the ambient air. As a result, a hollow tube can connect an evacuated volume to the open air without compromising the vacuum. This is a “windowless window.” An array of such tubes can be assembled together to increase the area of the aperture.

Abstract: A dynamic aperture is disclosed. A dynamic aperture includes a base layer, a conductive structure disposed on the base layer, and a layer of a material having a dynamically controllable electrical conductivity that is disposed over the base layer and the conductive structure. A transmission profile of the dynamic aperture is determined by a combination of the conductive structure and the layer of the material. The transmission profile is dynamically alterable by controlling the electrical conductivity of the layer of the material.

Abstract: A controllable frequency selective surface. The frequency selective surface has a plurality of conductive patches with integrated circuits straddling gaps between, and connected to, pairs of patches separated by gaps. Each integrated circuit presents a controllable impedance and as a result the characteristics of the frequency selective surface are controllable.

Abstract: 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.
