Ranging performances

5.1

Measurement conditions

In all measurement tables of the document, it is considered that:

The full field of view (FoV) is covered (typically 27°) or a partial FoV is covered after a

specific ROI definition by the user (array size from 4x4 SPADs to 16x16 SPADs).

Charts used as targets are: grey (17% reflectance, N4.74 Munsell) and white (88%

reflectance N9.5 Munsell).

Nominal voltage (2.8 V) and temperature (23°C).

Unless mentioned, the device is controlled through the driver using the default settings

(refer to the user manual for driver settings description).

Detection rate is considered as 94%.

Indoor (no IR) means there is no contribution of light in the band 940 nm ± 30 nm.

Outdoor overcast conditions means an illumination level of 0.7 W/m² back on the

sensor, in the band 940 nm ± 30 nm.

No coverglass is present

A gain correction is available in the driver. The performance assumes average gain

correction has been applied

5.2

Minimum ranging distance

The minimum ranging distance guaranteed is 4 cm. This is valid for all modes (ranging,

scanning, lite, and autonomous)

5.3

Ranging and Scanning modes: multi object detection

Thanks to direct time of flight principle and ST patents, the VL53L1 is able to detect up to



4 objects in the FoV.

The typical depth separation between objects has to be at least 80 cm.

5.4

Ranging and Scanning modes: full FoV performance

With default software driver settings, performances with full field of view (grey and white

targets) with 16 ms timing budget are provided in Table 14.
