Example for a sensor hardware:

There should be no common window in front of the emitter

and detector in order to avoid crosstalk by guided light

through the window.

The logarithmic characteristic of the AGC in the TSSP4P38

results in an almost linear relationship between distance and

pulse width. Ambient light has also some impact to the pulse

width of this kind of sensor, making the pulse shorter.
