两个VL6180x传感器可以相互间隔10厘米安装吗

你好杰里，
 
 
以下是您的问题的答案。
 
 如果您安装两个相距10厘米的传感器并同时启动两个传感器的距离测量，那么它们将相互干扰。考虑到您的应用，您需要两个传感器来测量物体的厚度，这可以通过HOST处理器的一些帮助来完成。可以使用一个传感器来连续检测是否存在放置在视野中的物体以进行测量。一旦检测到物体，HOST处理器就可以从第二个VL6180X启动单次测距测量。最终结果是来自两个传感器的测量，这将允许HOST处理器计算所讨论的材料的厚度。
使用两个彼此面对的传感器的第二种方法是使用范围测量周期，寄存器0x001B，功能。此功能可以设置为所需的“采样”速率。如果将测量周期设置为最大收敛时间设置的4倍，并且测量开始彼此异相，则VL6180X设备不会立即相互干扰。然而，它们最终会相互干扰，但这种干扰的时间尺度尚不清楚，因为这取决于内部振荡器随时间的漂移。

Hello Jerry,



Here are the answers to your questions.

If you mount two sensors 10 cm apart and initiate a range measurement from both of them at the same time then they will interfere with each other. Considering your application where you want two sensors to measure the thickness of an object, this can be done with some help from the HOST processor. One sensor can be used to continuously detect if there is an object placed in the field of view for measurement. Once an object is detected the HOST processor can initiate single-shot range measurements from the second VL6180X. The end result is measurement from both sensors which will allow the HOST processor to calculate the thickness of a material in question.
The second way to use two sensors facing each other is to use the range intermeasurement period, register 0x001B, feature. This feature can be set for a desired “sampling� rate. If the intermeasurement period is set to 4 times the max convergence time setting and the measurements are started out of phase to each other then, the VL6180X devices will not interfere with each other immediately. However, they will interfere with each other eventually but the timescale for this interference is not known as this depends on internal oscillator drifts over time.

For the sample code, I can definitely send you an example using our STM32 primitives. Please email me at
