VL53L8CX - Range Data Preprocessing designed for mobile phone requirments

Paul_Anthony · ‎2024-06-13

I just wanted to check the validity of an old post from 2022.

The VL53L8CX, like other TOF devices returns a 8x8 grid of distances.

The distances are tuned, so if a flat surface for example a wall is directly in front of the sensor (sensor is facing the wall with no offset or rotation) at a distance of 1 metre. Then all the 8x8 Zones will report a distance of 1 metre (assuming no floor, ceiling etc..., so there are no other reflections etc...). The measured distances are in fact larger for angles offset from zero, but they compensated for the requirements of the mobile phone manufacturers etc...

Is this still true.

Hello

The post from 2022 is still valid.

Like for other sensors, all the 8x8 zones will report the same distance and there is a compensation due to the angles.
