红外科技是啥意思啊（科技红外是什么）
红外线是一种电磁能量波和太阳可见光线类似，但是具有相比更长的波长。人眼是看不见红外的，只有在极高温度条件下（如物体燃烧温度），物体才能发射可见光线，但是在平常温度条件下，所有物体都能发射红外线。Infrared is an energy similar to visible light but with a longer wavelength. Infrared energy is invisible to the human eye however while visible light energy is emitted by objects only at a very high temperature infrared energy is emitted by all objects at ordinary temperatures.
场景中不同物体的温度变化可以通过红外线被红外热像仪感知，产生的红外视频图像反映场景中各种物体的温度特征。这些红外视频图像可以在普通的显示器被实时显示。在红外热像仪中，红外线首先被红外光学镜头聚焦在红外探测器上，然后红外信息被传输到红外热像仪的电子组件中进行图像处理，红外热像仪的电子组件对信号进行处理转换为标准图像可以被普通显示器实时显示给监视人员。Since thermal imagers sense infrared energy which varies with the temperature of objects in a scene the image generated provides a thermal signature of the scene. This image can be displayed on a standard video monitor. Infrared energy from objects in a scene are focused by optics onto an infrared detector. The infrared information is then passed to sensor electronics for image processing. The signal processing circuitry translates the infrared detector data into an image that can be viewed on a standard video monitor.
随着技术进步，红外热像仪逐渐变得便宜耐用，红外热像仪不仅让你看到黑夜，而且可以增强你感知危险目标，人员和动物相比背景具有更高的温度，因此红外热像仪相比人眼在白天，黑夜或者非常恶劣天气条件下，可以看得的更好更清晰。而且，具有测温功能的红外热像仪，可以实时感知人员温度，在当前新冠疫情肆虐情况下为公众提供更好的保护。
These systems are affordable and reliable. Thermal imaging systems not only let you see in the dark but they also enhance your ability to detect critical objects. Warmer objects such as people and animals stand out from typically cooler backgrounds. Thermal imaging systems see better than the unaided eye in daylight night and most poor weather conditions.
