Effective zone orientation

The VL53L8CH module includes a lens over the Rx aperture, which flips (horizontally and vertically) the captured

image of the target. Consequently, the zone identified as zone 0, in the bottom left of the SPAD array (see

Figure 26. Effective orientation), is illuminated by a target. This target is located at the top right-hand side of the

scene.

Measurement conditions

The following criteria and test conditions apply to all the characterization results detailed in this section unless

specified otherwise:

•

The specified target fills 100% of the FoV of the device (in all zones).

•

Targets used are Munsell N4.75 (17%), Munsell N8.25 (54%), and Munsell N9.5 (88%).

•

AVDD is 3.3 V, IOVDD is 1.8 V, and CORE_1V8 is 1.8 V.

•

Nominal ambient temperature is 23°C.

•

Maximum range capability is based on a 90% detection rate. (1)

•

Range accuracy figures are based on 2.7 sigma. This means that 99.3% of measurements are within the

specified accuracy.

•

Tests are performed in the dark and at 2 W/m2 target illumination (940 nm). A 2 W/m2 target irradiance at

940 nm is equivalent to 5 kLux daylight.

•

All tests are performed without cover glasses with a crosstalk margin set to 0 kcps.

•

The sensor relies on default calibration data.

•

The device is controlled through the API using the default driver settings.

1. Detection rate is a statistical value indicating the worst case percentage of measurements that return a valid ranging. For

example, taking 1000 measurements with a 90% detection rate, gives 900 valid distances. The 100 other distances may be

outside the specification, or flagged with an invalid target status.
