Abstract:
A method and apparatus for scanning an input beam of light in a two dimensional pattern; splitting the scanned input beam of light into two output beams of light, each one of the two output beams of light passing along a different path to a common region in a recording medium, such region scanning the recording medium during the scanning of the input beam of light to produce a diffraction grating in the recording medium by interference between the two output beams of light.
