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。

Available sensors include a vision sensor (color monoscopic camera), range sensors (sonars and IR detectors), and bumpers for collision detection.

可用的传感器包括视觉传感器(彩色照相机)、范围传感器(声波和红外探测器)以及碰撞检测的缓冲。

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.
