For more details on SPAD and temperature calibration please refer to the VL53L0X API

User Manual.

2.3.2

Ranging offset calibration

Ranging offset can be characterized by the mean offset, which is the centering of the

measurement versus the real distance.

Offset calibration should be performed at factory for optimal performances (recommended

at 10cm). The offset calibration should take into account:

•

Supply voltage and temperature

•

Protective cover glass above VL53L0X module

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.

Full offset and cross-talk calibration procedure is described in the VL53L0X API User

Manual.
