Proximity detection with auto calibration

An optical device (1) comprises an emitter (3) for emitting light, a receiver (4) for receiving reflected light and providing a data signal (15), a register (5) for storing processing parameters comprising a baseline reference value (16), and a processing unit (6) for processing the data signal (15)...

Beschreibung
Zusammenfassung:	An optical device (1) comprises an emitter (3) for emitting light, a receiver (4) for receiving reflected light and providing a data signal (15), a register (5) for storing processing parameters comprising a baseline reference value (16), and a processing unit (6) for processing the data signal (15) using the processing parameters. The processing unit (6) is configured to compare the data signal (15) to the baseline reference value (16), and determine that a crosstalk calibration of the optical device is required based at least partially on the comparison.
