UNIFORMITY ADJUSTMENT METHOD FOR A DIODE-LASER LINE-PROJECTOR

UNIFORMITY ADJUSTMENT METHOD FOR A DIODE-LASER LINE-PROJECTOR

In a line projector a diode-laser beam having an elliptical cross-section is projected onto a Powell lens which spreads the beam to form a line of light. Distribution of power along the line of light is adjusted by rotating the diode-laser beam with respect to the Powell lens.
