How a light sensor works
Web26 de out. de 2024 · The sensor emits beams of infrared light aimed straight ahead, which are then reflected off any surfaces they hit. The sensor detects returning beams and measures the difference in time between emitting a beam and receiving it back. That way, it can estimate the distance the beams traveled with great accuracy and without … WebLight is emitted from light sources which goes across the pulse oximeter probe and reaches the light detector. If a finger is placed in between the light source and the light detector, the light will now have to pass through the finger to reach the detector.
