In infrared photography, the film or image sensor used within a digital camera is sensitive to infrared lighting, which allows the camera to pick up any light that's invisible to the human eye.
在红外线摄影中，数码相机上使用的胶片传感器或图像传感器对红外光感光，能让相机拾取人眼不可见的任何光线。
Hot areas glow orange in infrared light, revealing the active fire front on the south and west sides of the burned area. (the orange horizontal stripes are satellite sensor artifacts.)
红外线领域为橙色，主要活跃在燃烧区域的南面和西面(橙色横纹为人造的卫星传感器)。
The M1031-W also includes an integrated passive infrared sensor for motion detection, a white LED light, and two-way audio support with a built-in microphone and speaker.
M1031-W还包括一个适合移动侦测的集成被动红外传感器，白色LED灯，和支持内置麦克风和扬声器的双向音频。
Based on experiment study, several factors are analyzed in the design of infrared gas sensor in which infrared LED is used as light source, and four schemes are compared in this paper.
在实验研究的基础上分析了采用红外发光二极管为光源的气体传感器在设计中应考虑的几个因素。
Each unit houses a near-infrared (NIR) LED and monochrome CCD camera sensor, so as the red pigment in blood (hemoglobin) absorbs NIR light, veins appear as dark lines on the resulting image.
手指静脉识别仪包括近红外线LED灯和黑白相机传感器。 近红外LED灯发出近红外射线，当近红外射线穿透手指时，手指静脉的血红蛋白将吸收近红外光，因此，图像中静脉将变为黑色。
