A proximity sensor often emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal.
一个接近性传感器通常会发出电磁或静电场,或电磁辐射光束(例如红外),以及在外地或返回信号的变化看。
In that case, the array would transmit to the wrong beam, and the user might miss the return signal entirely.
在这种状况下,阵列就会把讯号发射给错误的波束,使得用户完全收不到传回的讯号。
