ST has developed and patented its own technology, called FlightSenseTM, using Time-of-Flight (ToF) principle in order to propose new generation of high-accuracy proximity sensors.

FlightSenseTM technology based products are packaged in a module that integrates the proximity sensor Single Photon Avalanche Diode (SPAD) array, Ambient Light Sensor (ALS) as well as the Vertical Cavity Surface-Emitting Laser (VCSEL) used by the proximity sensor feature, thus greatly easing the product integration.

Using a mature in-house imaging process and an in-house high-volume packaging solution, this advanced technology is ideally suited to a wide range of applications that require:

  • Competitive system cost
  • Very small package footprint
  • Low power consumption

FlightSenseTM technology can be used in a host of application areas where accurate ranging, that is target reflectance independent, is required; as conventional IR proximity sensor devices cannot output an absolute range measure in the same manner:

  • Communication and consumer: browsing, remote control, proximity sensing, autofocus assist
  • Home appliance: gesture for light management, robot cleaners, toys, drinking machines
  • Automotive: on-board computer control with gesture
  • Industrial: proximity and light detection, door control, robotics
