Laser diode modulator and method of controlling laser diode modulator

摘要

A method for adjusting a laser diode drive current pulse, comprises providing a power correction table comprising drive current pulse correction factors corresponding to counter positions. The method also comprises providing a jump table comprising counter position adjustments corresponding to correction factors. A count value of a position within the counter positions is maintained. Maintaining the count value comprises indexing the count value to the jump table and incrementing the count value for each of a series of pixel clocks. A correction factor is determined, wherein determining the current correction factor comprises indexing the count value to the power correction table.
