对于近距离，我们建议使用VL6180。它更便宜，也更简单。
但是如果你真的想使用VL53，请将传感器向后移动一点，这样你就可以保证目标不会接近几厘米。比这更接近，当光从目标反射到传感器，回到目标和传感器时，范围趋于上升。 6180有这个问题，但程度较小。
降低VCSEL的功率或使用较小的持续时间不能很好地工作。功率更低，VCSEL无法可靠地打开并缩短持续时间会导致其他问题。

For close ranges we recommend the VL6180. It's cheaper and less complex.
But if you really want to use the VL53, move the sensor back a bit so you can guarantee the target will come no closer than a few cm. Closer than that the range tends to go up as the light bounces from target to sensor, back to target and senor. The 6180 has this problem but to a smaller degree.
Lowering the power to the VCSEL or using a smaller duration doesn't work well. Less power, and the VCSEL doesn't turn on reliably and shortening the duration causes other issues.
