ABSTRACT:
An optical device for non-contact recording image information on a recording material which is stretched into a cylindrical configuration by a recording head which is mounted on the guide device for movement parallel to the cylindrical axis along the surface of the recording material, and has a plurality of light waveguides in the form of glass fibers having entrance ends receiving modulated light from individual sources and exit ends facing the recording material and being densely packed in a linear arrangement characterized by the recording head including at least one adjustment plate having a plurality of individual grooves with one groove being provided with each of the waveguides which are secured therein with the exit ends being oriented in a line extending perpendicular to the cylindrical axis and the recording head including a light source member containing the individual light sources for each of the waveguides arranged at the spacing corresponding to the spacing at the entrance ends of the waveguides so that when the member is secured to the recording head, the individual light sources are aligned with the respective entrance ends of the fibers. Preferably the end of the recording head facing the cylinder has a concave surface with a radius of curvature slightly larger than the radius of curvature of the cylinder and the head may have a pair of adjustment plates whose grooves are aligned in pairs to receive a single row of fibers or whose grooves are offset to form two closely spaced offset rows of fibers.
