ABSTRACT:
A color optical scanner for generating data representative of a color image of an object which is scanned including: a linear sensor array located on an image plane for generating a data signal indicative of the intensity of light impinged thereon and having sensor sampling intervals of a predetermined length; an imaging assembly for imaging a moving scan area on the object containing a plurality of scan lines on an image plane and for defining an imaging light path extending from the scan area on the object to the image plane; a color wheel positioned along the imaging light path and having an axis of rotation extending transversely of the light path and having a plurality of faces adapted to be sequentially rotated into intersecting relationship with the light path; a plurality of the faces including a plurality of filter portions of different spectral range transmissibility which are sequentially rotated into intersecting relationship with the light path during different color imaging intervals having durations equal to the sensor sampling interval.
