ABSTRACT:
A laser data transfer system includes a laser for transmitting data, a communication link and a receiver which detects light transferred over the link and monitors the data encoded by the light for transmission errors. There are numerous causes for transmission errors, including: laser fatigue due to aging, fluctuations in temperature, a partially or fully occluded optical data path, or a laser lens which is out of focus. The receiver compensates for these errors by communicating occurrences to the transmitting processor which reacts by adjusting the laser drive current.
