摘要： An active, transparency-controlled window comprises at least one layer of a material that is transparent to at least selected wavelengths of light; at least one layer of photochromic material having a transparency, to the at least selected wavelengths of light, that can be controllably altered by an activating light; and a controllable source of light that activates the photochromic material to controllably alter the transparency of the photochromic material to the at least selected wavelengths of light. The material that is transparent to at least selected wavelengths of light may be a material selected from the group consisting of glass and plastic.

摘要： Aspects of embodiments pertain to a sensing systems configured to receive scene electromagnetic (EM) radiation comprising a first wavelength (WL1) range and a second wavelength (WL2) range. The sensing system comprises at least one spectral filter configured to filter the received scene EM radiation to obtain EM radiation in the WL1 range and the WL2 ranges; and a self-adaptive electromagnetic (EM) energy attenuating structure. The self-adaptive EM energy attenuating structure may comprise material that includes nanosized particles which are configured such that high intensity EM radiation at the WL1 range incident onto a portion of the self-adaptive EM energy attenuating structure causes interband excitation of one or more electron-hole pairs, thereby enabling intraband transition in the portion of the self-adaptive EM energy attenuating structure by EM radiation in the WL2 range.
