ABSTRACT:
Apparatus and method of non-mechanical scanning a laser diode light beam by altering the wavelength of the beam through changes in current applied to the diode and applying the beam to a diffraction grating to change the position of the beam as it emerges from the grating. A second dimension is scanned by the employment of an acousto-optic deflector and electronic driving and control means to change the position of the beam as it emerges from the deflector.
