And the hack only seems to work on plastic keypads — metal returns too much heat noise for the IR camera to reliably discern with keys were just pressed.

而且黑客似乎只能在塑料键盘上运用这个方法，因为金属会反射出大量的热量干扰波，从而使得红外摄相机无法准确识别。

Since most camera flashes emit IR along with their burst of visible light, the one substitution allowed the prototype to transmit and record infrared light.

由于大多数相机闪光灯在发出可见光同时就会发射出红外线，这一替换使得原型机能够发送并记录红外线。

LOTHAR (Land Optronic thermal Aiming Resource) is a multi sensor system specifically designed for Fire Control Systems equipped with the "Tilde" thermal camera (ir cooled).

Lothar系统是一种多传感器系统，专为配备“蒂尔德”热成像仪(红外制冷)的火控系统设计。

The next step in moving this technology to the field is to develop a portable tripod-based system that houses both the laser source and the IR camera.
