Physical Sciences Inc. (PSI) has been awarded a Phase II STTR contract from the US Army to develop and mature a fast, frequency-agile, stimuli-responsive, and tunable optical filters that autonomously protect sensors from damaging optical beams, while allowing unobstructed transmission of non-damaging wavelengths and intensities. With our university partner, PSI is developing a technology that that uses amplified free carriers to attenuate more than 99.9% of a high power incident pulse. An individual device will be able to protect against unknown threats across a broad bandwidth (e.g. the full visible) and the concept can be designed to operate in the visible, near infrared and short wave infrared bands, while exhibiting high transmission in the absence of high-intensity threats.
