Question

VL53L4CD TOF sensor - need accuracy at 10 cm (or perhaps in range 5 - 20 cm)?

I am looking into the VL53L4CD TOF sensor but find the specifications on distance accuracy at 10 cm (or perhaps in range 5 - 20 cm) to be murky at best.  I need to be able to determine distance to object with accuracy of 0.02 mm (0.001 inches) at this distance and be able to determine if object has moved in or out by that amount or more.  

Can this device produce that kind of accuracy? Other posts here make me think not, that all it can do is about 1 mm.

Also, the ST introductory webinar mentioned higher resolution project 55H2 if I heard it right. 

Can you provide any insights on that? 

Or suggest another product that can provide the accuracy / precision that I need, please.

Initially planning to use Arduino for the CPU processing.

Thank you.

Hello

The accuracy of the VL53L4CD can be found in the table 17 of the datasheet. Unfortunately, the VL53L4CD accuracy is at least +/-6mm with a timing budget of 33ms on a 17% white target. 
With ToF it is today difficult to get an accuracy lower than 1mm.
