Abstract:
Briefly, in accordance with one or more embodiments, time averaged Moiré patterns may be utilized in a scanned beam display having a Gaussian beam profile or the like in order to tailor uniformity of the image by controlling both the near field and far field regions of the display to result in a stable and uniform scanned beam display image. Consideration is made regarding the light source parameters of focus numerical aperture, profile, shape, and/or wavelength to achieve higher uniformity and stability without resulting in significant visible coherent artifacts such as tiled intensity patterns and/or Moiré.
