Description

The VL53L1X is a state-of-the-art, Time-of-Flight
(ToF), laser-ranging sensor, enhancing the ST
FlightSense product family. It is the fastest
miniature ToF sensor on the market with accurate
ranging up to 4 m and fast ranging frequency up to
50 Hz
Housed in a miniature and reflowable package, it
integrates a SPAD receiving array, a 940 nm
invisible Class1 laser emitter, physical infrared
filters, and optics to achieve the best ranging
performance in various ambient lighting conditions
with a range of cover window options.
Unlike conventional IR sensors, the VL53L1X uses
ST’s latest generation ToF technology which allows
absolute distance measurement whatever the target
color and reflectance.
It is also possible to program the size of the ROI on
the receiving array, allowing the sensor FoV to be
reduced.
