Abstract
Aliasing in detected image samples is substantially reduced by a spatial low-pass prefilter employing a diffusing surface variably spaced from an imager and situated in the path of projected image light to cause greater blurring in lower resolution regions of the imager than in higher resolution regions thereof, such that the cutoff spatial frequency varies continually in accordance with the variable resolution of the system.
