Abstract
An optical system for wireless data communication between the sensor electronics on a rotary shaft and the fixed data processor is disclosed. A first ring carrying IR LEDs is mounted to rotate with the shaft. A second ring carrying a photodetector is mounted adjacent to the first ring but does not rotate with the shaft. In the disclosed embodiment, both rings have LEDs and a photodetector so data and/or information can be transferred both to and from the shaft.
