How did work VL53L0X calibration process

[JKyun.11]

We are conducting study on mapping using VL53L0X proximity sensor to your company. But we met some problems while we were researching.

​

To proceed with the mapping, we need to know exactly what the value returned by the sensor means. So it's important to know what values this sensor gets and how it calculates the distance.

​

For example, only complete FOV covered experimental data exists in your data sheet. However, we should be able to predict how the data will come out if there are two or more objects in the sensor range, if one object is partially FOV covered, and if the sensor detects a tilted object.

​

We can't know this information just by the data sheet provided on the website. Would you be able to help me.

In order to get more data, you really should use the VL53L1CB. This sensor does everything the VL53L0X does and more. And the 'more' is what you want.

The L1CB captures the number of photon strikes in each clock cycle and bins them into a histogram. Then, when the range completes, the histogram data is uploaded to your MCU where it is processed. With histograms we can detect multiple targets in the field of view - if they are 80cm apart in depth.

And you can examine the Histogram data to draw your own conclusions.

Give the VL53L1CB a try. You will like it.
