Inside, a pair of infra-red sensors are measuring the absorption and scatter of the light to work out how much fat you're carrying.
不反射或发射任何红外能量的物质称为黑体,也不知道自然存在。
Materials which do not reflect or transmit any IR energy are known as Blackbodies and are not known to exist naturally.
样品吸收的红外光的特征波长类似于分子指纹,揭示其化学成分。
The characteristic wavelengths of infrared light that are absorbed by the sample are akin to a molecular fingerprint, revealing its chemical composition.
此外,文件还披露了磁,电磁和红外数据,以及潜艇鱼雷发射系统的规格和战斗系统等详细信息。
It also discloses magnetic, electromagnetic and infra-red data as well as the specifications of the submarine's torpedo launch system and the combat system.
红外能量沿源直线传播,并可通过其路径中的材料表面反射和吸收。
IR energy travels in straight lines from the source and can be reflected and absorbed by material surfaces in its path.
这些传感器通常安装在门上,并且它们发射的电磁或红外光束,并寻找变化的预测字段。
These sensors are usually mounted above the door, and they emit an electromagnetic or infrared beam and look for changes in the projected field.
不反射或发射任何红外能量的物质称为黑体,也不知道自然存在。
Materials which do not reflect or transmit any IR energy are know as Blackbodies and are not known to exist naturally.
Critical to complete the F/A-18C and F-16C, will be the inclusion of completed air-to-ground(AG) radar and Forward-Looking Infrared(FLIR) sensor systems.
红外光还可以揭示食品的分子组成,从而立即判断它是否安全。
The IR light can also reveal the molecular composition of a food product and thereby show immediately whether or not it is safe.
在这些图像中,不同的颜色对应着不同波长的红外光,这是人眼无法看到的。
In these images, different colors correspond to different wavelengths of infrared light, which are not visible to the human eye.
只要符合安全标准,当然必须接受新技术,例如接近传感器和红外摄像机来取代肉眼。
As long as safety standards are met, surely, they must accept new technologies such as proximity sensors and infra-red cameras to replace the naked eye.
这就是,我们想用它的红外为什么选择远程控制的目的的原因之一,但我们不希望看到它。
That's one of the reasons why IR is chosen for remote control purposes, we want to use it but we're not interested in seeing it.
研究人员介绍,这款软件还可以用于其它使用LED或红外激光的光疗法。
According to the researchers, the software could also be used with other light therapies that use LEDs or infra-red lasers.
