Abstract: A real-time ablation sensor uses an optical detector, such as a spectrometer or radiometer, to detect ablation of a material, for example by detecting a signal indicative of ablation of the material, which may be an engineered material. The optical detector may detect reflected light, either from the material being ablated, or from products of the ablation, such as in the vicinity of the material being ablated. A light source may be used to provide light that is reflected by the material and/or the ablation products, with the reflected light received by the detector. The light may be of a selected wavelength or wavelengths, with the selection made in combination with the selection/configuration of the material to be ablated, and/or the selection/configuration of the optical detector.

Abstract: An optical window for a hypersonic vehicle includes a window substrate and an optical coating on the window substrate, with the coating including multiple alternating layers of different materials. The coating may have many layers, for example having five or more alternating bi-layers and may be configured to still perform its optical function with some of the layers removed, such as by ablation of some of the layers through exposure to hypersonic flow. The different materials of the different layers may have different properties, for example with one of the materials being more resistant to ablation and/or chemical reaction than another of the layers. Coatings for anti-reflection additionally include a region of graded optical index between the sequence of bi-layers and the substrate. The hypersonic vehicle may include an optical sensor which operates by receiving light through the optical window.

Abstract: A window installation includes a phase-change filler material sealing an outer edge of the window, and coupling the window to a frame around the window. The filler material in a solid state rigidly holds the window in place. When the filler material is in a liquid state it allows the window to float in its coupling to the frame. There may be supports within the rigid material that contact the window, but allow the window to expand or contract by sliding along the supports. The installation may be useful in situations where the window is subjected to thermal shocks, or other sorts of heating. The installation may be used for a sensor window, and may be part of a hypersonic vehicle.

Abstract: A virtual adhesion method is provided. The virtual adhesion method includes increasing a magnetic characteristic of an initial structure, supporting the initial structure on a surface of a substrate, generating a magnetic field directed such that the initial structure is forced toward the surface of the substrate and forming an encapsulation, which is bound to exposed portions of the surface, around the initial structure.

Abstract: A thermal detection system for detecting a thermal profile of an optical window may be used in an airborne body that contains a sensor system. The system may include a thermal imager arranged within the airborne body for imaging a portion of the optical window and the portion may coincide with an optical path of the sensor system. The system may further include a processor in communication with the thermal imager for receiving images of the portion and determining a thermal gradient of the portion. The processor may be configured to apply corrections to active optical elements of the sensor system to accommodate for adverse thermal effects on the optical sensor that interferes with the sensor system performance.
