Figure 9. Typical initialization / ranging / housekeeping phases

2.6.1

Initialization and load calibration data phase

Initialization and calibration phase is performed before the first ranging or after a device

reset, see Figure 9.

The user may then have to repeat the temperature calibration phase in a periodic way,

depending on the use case.

For more details on the calibration functions please refer to the VL53L0X API User Manual.

2.6.2

Ranging phase

The ranging phase consists of a range setup then range measurement.

During the ranging operation, several VCSEL infrared pulses are emitted, then reflected

back by the target object, and detected by the receiving array. The photo detector used

inside VL53L0X is using advanced ultra-fast SPAD technology (Single Photon Avalanche

Diodes), protected by several patents.

The typical timing budget for a range is 33ms (init/ranging/housekeeping), see Figure 12,

with the actual range measurement taking 23ms, see Figure 9. The minimum range

measurement period is 8ms.
