STMicroelectronics’ Time-of-Flight (ToF) sensors use the speed of light to measure distances, enabling a wide range of applications in various industries. Here's an overview of how these sensors work and some of their key features:
How TOF Sensors Work
Principle of Operation: ToF sensors emit light pulses, typically from a laser or LED, and measure the time it takes for the light to travel to an object and back to the sensor. This time delay, multiplied by the speed of light, gives the distance to the object.
Light Emission and Detection: The sensor emits a modulated light signal. The light reflects off surfaces and returns to the sensor’s photodetector. The sensor calculates the distance based on the time delay between emission and detection.
Accuracy and Resolution: The accuracy of ToF sensors depends on the precision of the time measurement and the wavelength of the emitted light. Advanced sensors can measure distances with high precision, often down to millimeters.
