Abstract
A rotating surface optical sensing system having a radiation source controlled by a controlled current generator to emit electromagnetic radiation toward the rotating surface from which it can be directed to a radiation detector to provide corresponding signals to a threshold detector. The controlled current generator uses the threshold detector indications as to whether these signals are beyond a threshold value if validated by a rotation determiner noting rotations of the rotating surface to set the current for the radiation source.
