Time-of-flight sensor

14 November 2018 Analogue, Mixed Signal, LSI

The VL53L1X time-of-flight sensor from STMicroelectronics, extends the detection range of the company’s FlightSense technology to four metres, bringing high-accuracy, low-power distance measurement and proximity detection to an even wider variety of applications.

Unlike other proximity sensors that use simple infrared 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.

With low power consumption and fast ranging performance, the VL53L1X is ideal for mobile robotics for wall following, cliff detection, collision avoidance and hover/landing assistance for drones or unmanned aerial vehicles (UAVs). The power-saving presence detection mode enables innovative auto-sleep/wake-on-approach use cases.

The fully integrated device measures only 4,9 x 2,5 x 1,56 mm, and contains the laser driver and emitter, as well as the single-photon avalanche diode (SPAD) light receiver that gives the sensor its ranging speed and reliability.
