Array size is quess based on image.
I was able to see external laser pointers dot in intensity part of dataflow, which matched array horizontal positions.
Laser pointer didn't interference with measurement.
I think distance is calculated from phase difference of transmitted and received modulated laser pulse.(+light intensity)
if i meassure 3729mm i get the result 0d1b hex
