Sensing media speed |
摘要 |
A method of using electromagnetic radiation to control exposure of media to electromagnetic radiation is presented. The method includes rotating the media and sensing a frequency of electromagnetic radiation radiating from a rim of the media with a stationary detector. Exposure of the media to electromagnetic radiation with a movable source is controlled with the sensed frequency to provide increased accuracy.
