透明物体范围测量传感器测量背景而不是物体

你好Heri，
 
 
 由于VL6180X器件使用聚焦激光束作为光源，因此可以通过透明玻璃或塑料轻松传输。塑料将允许一些光线反射回传感器，然而，与位于透明塑料背面的一块材料相比，这将是最小的。如果要查看塑料对信号返回的影响，请从塑料背面取下一块材料。没有这种材料的返回信号速率将是来自塑料的返回信号。要获得此返回信号速率，请读取RESULT__RANGE_RETURN_RATE，寄存器0x0066。
 
 如果您想检测一块塑料远离VL6180X的距离，可以考虑使用不透明塑料，使光子反弹回传感器并报告距离。
 
 谢谢，

Hello Heri,


As the VL6180X device uses a focused laser beam for its light source, it will trasmit fairly easily through clear glass or plastic. The plastic will allow some light to bounce back into the sensor, however, this will be minimal compared to a piece of material located at the back of your clear plastic. If you want to see the effect of your plastic on the signal return, remove the piece of material from the back of the plastic. The return signal rate without this material will be the return signal from the plastic. To get this return signal rate, read RESULT__RANGE_RETURN_RATE, register 0x0066.

If you want to detect how far a piece of plastic is away from the VL6180X, consider using opaque plastic that will allow the photons to bounce back into the sensor and report a distance.  

Thanks,
Colin
