2.3.3 Cross-talk calibration
Cross-talk is defined as the signal return from the cover glass. The magnitude of the cross-
talk depends on the type of glass and air gap. Cross-talk results in a range error which is
proportional to the ratio of the cross-talk to the signal return from the target.
Figure 8. Cross-talk compensation
Full offset and cross-talk calibration procedure is described in the VL53L0X API User
Manual.
2.4 Ranging operating modes
There are 3 ranging modes available in the API:
1. Single ranging
Ranging is performed only once after the API function is called.
System returns to SW standby automatically.
2. Continuous ranging
Ranging is performed in a continuous way after the API function is called. As soon as
the measurement is finished, another one is started without delay.
User has to stop the ranging to return to SW standby. The last measurement is
completed before stopping.
3. Timed ranging
Ranging is performed in a continuous way after the API function is called. When a
measurement is finished, another one is started after a user defined delay.
This delay (inter-measurement period) can be defined through the API.
User has to stop the ranging to return to SW standby.
If the stop request comes during a range measurement, the measurement is completed
before stopping. If it happens during an inter-measurement period, the range measurement
stops immediately.
