Abstract

Abstract

A variable attenuator for high-powered IR beams, based on MEMS-controlled excitation of surface plasmon polaritons on suitably conducting surfaces is described. Materials choice determines the useful spectral band. Intensity variation over nine-orders is theoretically possible.

Abstract

Abstract

Room-temperature microbolometer arrays with sensitivity in narrow wavelength bands for spectral imaging in the mid-wave and long-wave infrared are described. The approach is based on vanadium-oxide air-bridge bolometers that are integrated with plasmonic resonant absorbers to maintain response speed without adding processing complexity.

Abstract

Abstract

A structured thin film with widely variable long-wave emissivity and insignificant change to its visible reflectance is proposed and demonstrated theoretically. An application is dynamic Identification Friend or Foe (IFF) panel viewable at LWIR but optically invisible.

Abstract

Abstract

Fast optical limiters are needed to protect sensors from intense short laser pulses. An optical limiter design based on a conducting-oxide grating with a large nonlinear refractive index at the plasma frequency is proposed and investigated.
