Waveguide imaging system

Claim 2

A waveguide system for forming a line pattern of illuminated and non-illuminated bits on an imaging surface, the system comprising: (a) an imaging member having an imaging surface; (b) a unitary waveguide means for guiding radiation propagating therein, the unitary waveguide being formed from identical elastomeric material and shaped so as to include a coupling means for coupling light into the waveguide means, lens means for collimating the light and a plurality of individual waveguide means arranged substantially parallel to each other in substantially the same plane, the plane being oriented with respect to the imaging surface so that light emanating from the waveguide system impinges the imaging surface to form a line of bits; and (c) field means comprising electrodes positioned on either side of the individual waveguide means so that, when subjected to voltage pulses, the field between the electrodes will attract the electrodes toward each other, altering the dimensional cross-section of the waveguide means between the charged electrodes and attenuating the light propagating therethrough to produce on the imaging surface a line pattern of illuminated and non-illuminated bits.

Claim 3

The waveguide system of claim 1 further including a means for line-by-line indexing of the imaging surface with respect to the waveguide means, the indexing being coordinated with voltage pulse input to the field means.

Claim 4

A waveguide system for forming a line pattern of illuminated and non-illuminated bits on an imaging surface, the system comprising: (a) an imaging member having an imaging surface; (b) a unitary waveguide means for guiding radiation propagating therein, the unitary waveguide being formed from identical sputtered glass material and shaped so as to include a coupling means for coupling light into the waveguide means, lens means for collimating the light and a plurality of individual waveguide means arranged substantially parallel to each other in substantially the same plane, the plane being oriented with respect to the imaging surface so that light emanating from the waveguide system impinges the imaging surface to form a line of bits, at least the individual waveguide means having a coating of liquid crystal material; and (c) field means comprising electrodes arranged on opposite sides of the individual waveguide means so that, when a field is established between the electrodes the orientation of the liquid crystal molecules is changed and the propagating ability of the waveguide means is altered to produce on the imaging surface a line pattern of illuminated and non-illuminated bits.

Claim 5

A waveguide system for forming a line pattern of illuminated and non-illuminated bits on an imaging surface, the system comprising: (a) an imaging member having an imaging surface; (b) a unitary waveguide means for guiding radiation propagating therein, the unitary waveguide being formed from identical sputtered glass material and shaped so as to include a coupling means for coupling light into the waveguide means, lens means for collimating the light and a plurality of individual waveguide means arranged substantially parallel to each other in substantially the same plane, the plane being oriented with respect to the imaging surface so that light emanating from the waveguide system impinges the imaging surface to form a line of bits, at least the individual waveguide means having a coating of liquid crystal material; and (c) field means comprising electrodes arranged on opposite sides of the individual waveguide means so that, when a field is established between the electrodes the orientation of the liquid crystal molecules is changed and the propagating ability of the waveguide means is altered to produce on the imaging surface a line pattern of illuminated and non-illuminated bits.

Claim 6

The waveguide system of claim 3 further including a means for line-by-line indexing of the imaging surface with respect to the waveguide means, the indexing being coordinated with voltage pulse input to the field means.
