time of flight tof sensors

Innovative Time-of-Flight Sensors

1 billion ToF modules shipped by ST Discover the newest additions to ST's ToF sensor portfolio: VL53L3CX and VL53L1, based on the ST patented FlightSense™ technology.
With patented histogram algorithms and innovative module construction, both Time-of-Flight ranging sensors are able to detect different objects within the field-of-view (FoV) with depth understanding.

VL53L3CX - Time-of-Flight ranging sensor with multi-target detection

The VL53L3CX measures the range to objects up to 5m, the result is unaffected by the target color or reflectance, unlike conventional infrared sensors. The ST Histogram algorithm allows designers to introduce powerful new features to their products, such as enabling occupancy detectors to provide error-free sensing by ignoring unwanted background or foreground objects, or reporting the exact distances to multiple targets within the sensor field-of-view.

Key features of VL53L3CX

  • Full FoV ranging: 500cm+ (white target, no IR)
  • High-performance proximity sensor
  • Excellent short distance linearity
  • Multi-target distance measurement based on ST Histogram patented algorithms
  • Immunity to cover glass cross-talk beyond 80cm
  • Automatic fingerprint smudge compensation
  • Miniature ToF product

VL53L1 - Time-of-Flight ranging sensor with advanced multi-zone and multi-object detection

The VL53L1 is able to range up to 8m indendent of the target color or material. The ST Histogram algorithm permits detection of different targets within the Field-of-View (FoV). The algorithm also provides immunity to cover glass cross-talk beyond 80cm. The SPAD array zone selection allows advanced multi-zone scanning. The VL53L1 also has a programmable FoV from 15° to 27° dependent on the size of the SPAD array zone selection.

Key features of VL53L1

  • Full FoV ranging: 8 meters under histogram
  • Multi-target distance measurement based on ST Histogram patented algorithms
  • Immunity to cover glass cross-talk beyond 80cm
  • Automatic fingerprint smudge compensation
  • SPAD array zone selection for FoV reduction
  • Integrated lens for long distance ranging
  • Better ambient light immunity
