Method and apparatus for blending regions scanned by a beam scanner

A method for blending illuminated regions in a field of view, comprising the steps of:

• generating a plurality of beams of light;
• directing the plurality of beams of light toward a scanner;
• scanning the plurality of beams of light across a field of view along fast scan and slow scan axes, wherein each of the plurality of scanned beams illuminates a respective region of the field of view that overlaps with at least one other of the respective regions adjacent in a dimension corresponding to the slow scan axis;
• and
• modulating the intensity of each of the plurality of beams of light to compensate for the illumination energy produced by the other beams.

An image capture device, comprising:

• a beam scanner operable to scan a plurality of beams across respective regions of a field-of-view, the regions having at least two dimensions corresponding to a fast scan axis and a slow scan axis, wherein each of the plurality of regions at least partially overlaps at least one other region aligned in a dimension corresponding to the slow scan axis;
• a detector aligned to receive beam energy scattered from the field-of-view and output an electrical signal corresponding to the received energy;
• and
• a controller coupled to receive the electrical signal from the detector and output a representation of the received beam energy.
