Abstract

An optical imaging system, as shown in the figure, comprises a unitary optical transmitting assembly 12 and an illumination source in the form of a pair of apertured fluorescent lamps 14, 15. A document 16, supported on document support 18a, 18b is moved through exposure zone 20 by means not shown.

An optical imaging system, as shown in the figure, comprises a unitary optical transmitting assembly 12 and an illumination source in the form of a pair of apertured fluorescent lamps 14, 15. A document 16, supported on document support 18a, 18b is moved through exposure zone 20 by means not shown.

The transmitting assembly 12 includes a linear array 22 of mutually coherent optical fibers which extend from the top through the bottom of array 22. The assembly 12 further includes a transparent light collection member 24, which consists of a pair of substantially identical semi-cylindrical light collectors 26, 28 and a pair of elongate members 34 and 36 having a lower surface at which the

other end of the fiber array terminates. These respective members are integrally bonded to each other by means of an adhesive 38 so as to provide a unitary optical element within which the optical fiber array 22 is sealed, the fibers being positioned adjacent to and perpendicular to the length of the light collectors 26 and 28, and being further supported through the element by each half of the members 34 and 36, 39.

According to the principles of the invention, a screening array is placed within member 36. Member 36 has at its apex a generally plane surface 40 sloping away from fiber array 22. The screening array 39 comprises a...
