    摘要： Method for limiting the amount of radiation impinging on a radiation sensitive detector (RSD) responsive to signals having infrared wavelengths of approximately 3 to 14 microns. Method includes: directing radiation signal through prism toward RSD; permitting radiation signal to impinge upon RSD when radiation is below predetermined threshold; and directing radiation associated with radiation signal but of different wavelengths from signals of interest on path external to prism, to initiate limiting of radiation impinging upon RSD when predetermined threshold is exceeded. Also, Total Internal Reflection device including prism having thin film coated on back surface of prism. Material making up prism and thin film are selected so that, in presence of radiation having intensity less than certain threshold, refractive index of thin film is lower than that of prism, and when radiation has intensity higher than that certain threshold, refractive index of thin film is higher than that of prism.

    摘要： An IR limiting device for a detector that is based on a micro-optomechanical cantilever array is disclosed. In the normal state, each microcantilever device in the array behaves like a mirror that reflects the infrared signal to the detector. The microcantilever device absorbs radiation outside the desired infrared region. When the radiation is stronger than a predetermined threshold, the microcantilever device bends as a result of thermo-mechanical forces, and it reflects the signal away from the detector, thereby limiting the radiation. The advantage of such a system is that each pixel in the detector can be addressed individually, and the limiting is localized.

    摘要： Method for limiting the amount of radiation impinging on a radiation sensitive detector that is responsive to signals of interest having infrared wavelengths of approximately 3 to 14 microns, such as an infrared camera. The method includes: directing a radiation signal through a prism and toward the radiation sensitive detector; permitting the radiation signal to impinge upon the radiation sensitive detector, e.g. upon an infrared focal plane array in the camera, when the radiation is below a predetermined threshold; and directing radiation associated with the radiation signal but having wavelengths different from said signals of interest—e.g., wavelengths in the visible and near-infrared range—on a path external to the prism, in order to initiate the limiting of the radiation impinging upon the radiation sensitive detector when the predetermined threshold is exceeded. Also, a Total Internal Reflection device that includes a prism having a thin film coated on the back surface of said prism. The material making up the prism and the thin film are selected so that, in the presence of radiation having an intensity less than a certain threshold, the refractive index of the thin film is lower than that of the prism, and when the radiation has an intensity higher than that certain threshold, the refractive index of the thin film is higher than that of the prism.

    摘要： An all-optical switching array for switching a direction of optical signals is presented. The all-optical switching array includes a first substrate. Furthermore, the all-optical switching array includes a plurality of optical switches disposed on the first substrate, wherein each of the plurality of optical switches comprises a first state and a second state and is configured to change the direction of an optical signal, depending on whether the optical switch is in the first state or the second state. The transition of the switch between the first state and the second state is triggered by an ultra-fast laser beam.

    摘要： Method for limiting amount of radiation impinging on a radiation-sensitive detector device by directing radiation toward the detector, permitting the radiation to impinge upon the detector device when the radiation is below a predetermined threshold, and utilizing radiation having wavelengths different from signals of interest to initiate limiting of the radiation impinging upon the detector when the predetermined threshold is exceeded. The optical limiter includes an IR limiting layer pair selected so that energy from visible and near infrared radiation activates the optical limiter. The limiting layer pair may includes a layer closer to the source of radiation of e.g. vanadium dioxide, vanadium sesquioxide, or germanium crystal and a layer further from the source of radiation of e.g. chalcogenide glass, germanium crystal, or sodium chloride crystal.
