Implementation of a Current Drive Modulator for Effective Speckle Suppression in a Laser Projection System
We report on the implementation of a current drive modulation circuitry that is effective in suppressing speckle noise for laser diodes. The drive circuit allows for operating the laser diode current at constant dc or modulating the current with square or triangular wave signals. We theoretically in...
