Abstract
An optical fiber array is used as a blur filter in imaging apparatus to limit high spatial frequencies incident upon an image sensor, and thereby to reduce undersampling artifacts. The optical fiber array is disposed in the path of incident image light a predetermined distance from the image sensor such that at least some of the optical fibers composing the array emit a cone of light over adjacent photosites, thereby producing a blurred image. The blurring effect can also be obtained by using a pseudo-random array of fibers, and the imaging assembly can be additionally simplified by using the fiber optic array as a protective cover plate for the sensor.
