    • Various embodiments are directed to a proximity sensor apparatus. A light source may emit light that is conducted through multiple optical fibers, each having a source end and an emission end. The multiple optical fibers emit the light out the emission end and are arranged such that the emission ends form a grid. Multiple photoelectric sensors, each substantially co-located with each of the multiple optical fibers at the emission end are operative to detect emitted light that has been reflected back off an object. A processing component may be communicatively coupled with the multiple photoelectric sensors and receive signals from the multiple photoelectric sensors. The signals may be indicative of the detected emitted light that has been reflected back. The signals may be processed to determine a distance from the multiple photoelectric sensors to the object that reflected the emitted light.
    • 各种实施例涉及接近传感器装置。 光源可以发射通过多个光纤传导的光,每个光纤具有源极端和发射端。 多个光纤将光从发射端发射出来,并且排列成使得发射端形成网格。 与发射端的多个光纤中的每一个基本上共同定位的多个光电传感器可操作以检测已被反射回物体的发射光。 处理部件可以与多个光电传感器通信耦合并从多个光电传感器接收信号。 信号可以指示被反射回来的检测到的发射光。 可以处理信号以确定从多个光电传感器到反射发射光的物体的距离。
