VL53L1X Ranging performances

3 Ranging performances

3.1 Test conditions

In all measurement tables of this specification, it is considered that:

1. The full FoV (typically 27 °) is covered or a partial FoV is covered after a specific ROI is

programmed by the user (array size from 4x4 SPADs to 16x16 SPADs).

2. Charts used as targets are: grey 17 % reflectance (N4.74 Munsell), grey 54 %

reflectance (N8.25 Munsell), and white 88 % reflectance (N9.5 Munsell).

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

4. Detection rate is considered as 100 %.

5. Unless mentioned, the device is setup and controlled through the driver using the

following settings:

a) Distance mode is long

b) Timing budget is 100 ms

c) No cover glass is present

d) Target covers the full FoV

6. Ambient light is defined as follows:

a) Dark = no IR light in the band 940 nm ±30 nm

b) 50 kcps/SPAD = lighting on a sunny day from behind a window

(a)

c) 200 kcps/SPAD = lighting on a sunny day from behind a window, with direct

illumination on the sensor

d) For reference, usual office lighting is around 5 kcps/SPAD

a. kcps is kilo counts per second. kcps/SPAD is the return ambient rate measured by the VL53L1X.
