STMicroelectronics has extended the capabilities of its FlightSense™ ToF ranging sensors by introducing the VL53L3CX with patented histogram algorithms that allow measuring distances to multiple objects as well as increasing accuracy.
The VL53L3CX measures object ranges from 2.5cm to 3m, unaffected by the target color or reflectance, unlike conventional infrared sensors. This 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’s field-of-view.
The ST patented histogram algorithms increase cover-glass crosstalk immunity and allow real-time smudge compensation preventing external contamination from adversely affecting the ranging accuracy of, for example, vacuum cleaners or equipment that may be used in a dusty industrial environment. Ranging under ambient lighting is also improved (more info).
