Abstract: A shortwave to midwave infrared (SWIR-MWIR) optical window includes a substrate formed from a nanocomposite optical ceramic material and a coating disposed on the substrate to provide electromagnetic interference (EMI) protection. The coating is electrically conductive and SWIR-MWIR transparent and comprises a doped zinc oxide material. A method of protecting an EO/IR sensor from electromagnetic interference (EMI) includes depositing a thin film electrically conductive and SWIR-MWIR transparent coating over a surface an optical window of the EO/IR sensor. The optical window is formed from a nanocomposite optical ceramic material and has a curved surface. The thin film electrically conductive and SWIR-MWIR transparent coating comprises an electrically conductive zinc oxide material.

Abstract: Systems and method for forming a nanocomposite material. One example of a nanocomposite material includes a first sulfur-based nanoparticle material defining a first nanophase and a second sulfur-based nanoparticle material defining a second nanophase, wherein the nanocomposite material is at least partially long-wave infrared (LWIR) transmitting, and the first nanophase and the second nanophase are co-dispersed to form interpenetrating networks with one another and each has a grain structure that is distinct from one another.

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.
