摘要： The invention concerns an infrared emitter is provided comprising a metalized membrane emitting infrared light in operation. The membrane comprises a two dimensional array of infrared wavelength sized through-holes and to each side a thin metal layer comprising also an array of through-holes. The through-holes are arranged as a two-dimensional periodic array and each of said through-holes have a cross section having a maximum and a minimum dimension of less than any wavelength of the emitted infrared light. The peak wavelength of the emitted infrared light is proportional to the periodicity of the through-holes.
At least one of the metal layers is connected to an electrical current source that provides an electrical current that heats at least one of the metal layers so that a narrow bandwidth and highly directive light beam of infrared light is emitted.
The membrane is arranged on a membrane support and both are made of a material that resists to temperatures higher than 400 °.摘要翻译： 本发明涉及一种红外发射器，其包括在操作中发射红外光的金属化膜。 该膜包括红外波长尺寸的通孔的二维阵列，并且每一侧均包括通孔阵列的薄金属层。 通孔被布置为二维周期性阵列，并且每个所述通孔具有的截面具有小于发射的红外光的任何波长的最大和最小尺寸。 发射的红外光的峰值波长与通孔的周期成正比。 金属层中的至少一个连接到电流源，该电流源提供加热至少一个金属层的电流，使得发射窄带宽和高度指向性的红外光光束。 膜被布置在膜支撑件上，并且两者均由耐受高于400°的温度的材料制成。
