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。
