人常说“时光不再倒流”,意思是逝去的事物是不可能再现的。但是,随着现代高新技术的发展,尤其是远红外技术的发展,人们或许可以追踪“过去”的踪影。最新技术水平的远红外探测器根据热成像技术,可以在某种程度上再现“过去”的事物。其原理为:任何物体本身都是一个“热源体”,它在空间上的任何移动、停留,都会留下人的眼睛所观察不到的“热成像”,但是,远红外探测器对此却可以一览无遗。 People often say that “the time is not going backwards,” which means that it is impossible to reproduce what was lost. However, with the development of modern high-tech, especially the development of far-infrared technology, people may be able to trace the “past”. The latest state-of-the-art far-infrared detectors can reproduce the “past” things to a certain extent based on the thermal imaging technology. The principle is that any object itself is a “heat source body”. Any movement or stay in space will leave “thermal imaging” that human eyes cannot observe. However, far-infrared detectors have It can be seen at a glance.
