1. A fiberoptic endoscope scanning system which comprises:

  • at least one multifiber for transmitting light from an object within a field of view from the distal end to the proximal end and to scan in a first mode a continuous region of the object;

    distal optics to form an image of the object on the distal end of the multifiber;

    means to effect simultaneously a second distinct chromatic scan to sweep out a region of the object; and

    optics at the proximal end for displaying the image substantially free of noise, the multifiber, the proximal and distal optics and the means to effect the chromatic scan all in optical communication with one another.
