    • 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.
    • 响应于具有大约3至14微米的红外波长的信号,限制照射在辐射敏感探测器(RSD)上的辐射量的方法。 方法包括:将辐射信号通过棱镜指向RSD; 当辐射低于预定阈值时允许辐射信号撞击RSD; 并且将与辐射信号相关联但与波长相关的辐射的辐射指向与棱镜外部的路径上的感兴趣的信号,以在超过预定阈值时开始限制入射到RSD上的辐射。 此外,全内反射装置包括具有涂覆在棱镜后表面上的薄膜的棱镜。 选择构成棱镜和薄膜的材料,使得在存在强度小于一定阈值的辐射的情况下,薄膜的折射率低于棱镜的折射率,并且当辐射的强度高于该特定阈值时,薄的折射率 胶片比棱镜高。

    • 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.
    • 用于限制辐射敏感检测器上的辐射量的方法,其响应于红外波长为约3至14微米的感兴趣信号,例如红外相机。 该方法包括:将辐射信号引导通过棱镜并朝向辐射敏感检测器; 允许辐射信号照射在辐射敏感检测器上,例如。 在相机中的红外焦平面阵列上,当辐射低于预定阈值时; 并且引导与辐射信号相关联的辐射,但是具有不同于感兴趣信号的波长(例如在可见光和近红外范围内的波长)在棱镜外部的路径上,以便开始限制辐射入射到 超过预定阈值时的辐射敏感检测器。 另外,全内反射装置,其包括具有涂覆在所述棱镜的后表面上的薄膜的棱镜。 选择构成棱镜和薄膜的材料,使得在存在强度小于某一阈值的辐射的情况下,薄膜的折射率低于棱镜的折射率,并且当辐射具有 强度高于该阈值,薄膜的折射率高于棱镜的折射率。
