这项技术被称为STEAM，即连续时间编码放大照相机。 它用一束红外激光照射物体，变换一系列不同的波长，每一个对应着传感器上的一个像素点。
The technology is dubbed STEAM, short for serial time-encoded amplified microscopy.
该相机的工作原理是：用一束激光照在物体上，每一个像素点都被不同红外频率的激光照着，以此来优化放大在其他情况下太弱而看不见的信号。
The camera works by illuminating objects with a laser that emits a different infrared frequency for every single pixel, allowing them to custom-amplify a signal that would otherwise be too dim to see.
在复杂红外背景中如果红外点目标所占的像素少，通常的检测方法就很难将目标检测出来，且往往会含有较多假目标。
It is hard to detect a small target in a complex background using a conventional algorithm, especially when IR target has few pixels, many fake targets will be detected.
