time-of-flight laser distance sensor / miniature
VL53L series STMicroelectronics



  • Technology:

    time-of-flight laser

  • Other characteristics:



ST has introduced a new generation of high-performance proximity and ranging sensors, based on FlightSense™ Time-of-Flight (ToF) technology.

Unlike other proximity sensors that use simple IR (Infra-Red) technology, which only measure signal strength and can be affected by the object’s reflectivity, FlightSense™ sensors directly measure distance to the object based on the time for emitted photons to be reflected, enabling accurate distance ranging regardless of the object’s surface characteristics.

FlightSense™ products are packaged in “all-in-one” miniature module which contain the laser driver and emitter as well as the Single Photon Avalanche Diode (SPAD) light receiver that gives ST’s sensors their unrivaled ranging speed and reliability.

This advanced ToF solution combines the benefits of ST’s unique SPAD technology with our mature in-house imaging process and high-volume packaging facilities. It is ideally suited to a wide range of applications that require:

Accurate and high-speed distance measurement
Low power consumption
Competitive system cost
Easy integration with flexible mechanical design
