红外辐射探测器由于具有在夜间和透过烟雾等产生图像的能力,已变得特别重要。常规的成像仪都具有用于获取图像像元的大面积探测器元件。这种探测器元件的长度和宽度均长于其捕获的辐射的波长。虽然常规红外探测器能够成功地产生有用的图像,但是它们在工作中会受到严格的条件限制。对于给定的入射辐射输入功率,这些器件 Infrared radiation detectors have become particularly important due to their ability to produce images at night and through smoke and the like. Conventional imagers have large area detector elements for acquiring image pixels. The length and width of such detector elements are both longer than the wavelength of the radiation they capture. Although conventional infrared detectors can successfully produce useful images, they are subject to severe constraints in their operation. For a given incident radiation input power, these devices
