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.

Abstract
A fiberoptic endoscope scanning system with multiple scanning modes. The first mode is a multifiber scanning along its longitudinal axis and a second scanning mode is a chromatic scan comprising a prism and/or grating at the distal end of the endoscope. The multiple scanning modes result in superior improvement in the image scan. The superior improvement in the clarity of the image scanned.

17. A method of scanning an object with a fiberoptic scanning system which includes:
-
transmitting light from an object within a field of view from the distal end of a multifiber to the proximal end; forming an image of the object on the distal end of the multifiber; scanning the object to sweep out sequentially a continuous region of the image in a first scanning mode; scanning simultaneously in a second distinct chromatic scanning mode to sweep out the region of the object; scanning in the second mode about a second axis displaced from the first axis; and displaying the image at the proximal end of the multifiber substantially free of noise. - View Dependent Claims (20, 21, 22)
