CORRECTION OF LASER DIODE BAR ERROR

1 . A method for dynamic correction of cross-array errors in an optical systems incorporating laser diode bar comprising:

emitting laser beams from a plurality of emitters on the laser diode bar;

analyzing the beams produced from each of the plurality of emitters;

measuring a deviation of each emitter relative to a straight line;

transferring the deviation for each of the emitters relative to the straight line to a controller; and

driving a plurality of actuators connected to micro-mirrors to correct for the deviation from the straight line of each of the emitters.

2 . The method according to claim 1 wherein the beams are analyzed by a multi-pixel light sensor device.

3 . The method according to claim 1 wherein each of the micro-mirrors is adapted to correct for the deviation of a single emitter.

4 . A method for dynamic correction of cross-array errors in an optical systems incorporating a laser diode bar comprising:

emitting laser beams from a plurality of emitters on the laser bar;

analyzing beams produced from each of the plurality of emitters;

measuring a deviation of groups of emitters relative to a straight line;

transferring the deviation for each of the groups of emitters relative to the straight line to a controller; and

driving a plurality of micro-mirrors actuators to correct for the deviation from the straight line of each of the groups of emitters.

5 . The method according to claim 4 wherein correction of the deviation the micro-mirror actuators is applied to the groups of emitters by averaging deviation produced by each group of emitters.

6 . The method according to claim 4 wherein the beams are analyzed by a multi pixel light sensor device.

7 . The method according to claim 4 wherein the beams are analyzed by a single pixel light sensor device.
