Abstract: A scanning apparatus is provided, which includes a fixed, hollow cylindrical segment (12) having a central longitudinal axis (16), the interior of which forms a concave surface for intimate contact with a medium for recording and/or readout, a support structure forming a transport for translational movement along the axis, a light source (18) mounted on the transport for movement therewith and for providing a beam capable of being directed along the axis, and a slanted mirror (26), angled 45 degrees with respect to the axis and mounted on the transport for translational movement therewith and for rotational spinning around the axis. The beam from the light source is reflected 90 degrees from along the axis along a radial to the medium and the rotation and translation cause the beam to scan the medium such that the rotating light beam is at all times perpendicular to the medium at the point of contact of the beam with the medium.

Abstract: The invention relates to a process and device for exposing imaging material. A light beam (2) generated in a light source (1) is modulated linewise during an exposure time in a video modulator (5) and deflected over the imaging material (9) by means of a light beam deflector (7). During a returm time following the exposure time the video modulator (5) is deactivated. To present back-reflections, between the light source (1) and the video modulator (5) there is an optical isolator (4) which is switched on during the exposure time by gate pulses. In oder to maintain a constant operating temperature of the optical isolator (4) during the exposure and return times, the optical isolator (4) is swiched on linewise by additional gate pulses (GI) during a compensation time within the return time, during which the optical isolator (4) heats up. The optical isloator (4) is controlled in such a way that the sum of the lenghts of the exposure time and the compensation time is fairly constant within each line.

Abstract: The invention relates to a light beam deflector consisting of a transparent deflecting prism (1) extending along an optical axis (3) and a carrier prism (2). The deflecting prism (1) has a light admission surface (5) substantially perpendicular to the optical axis (3) and a light emission surface (7). The carrier prism (2) is joined on the reflecting surface (4) to the deflecting prism (1), making the latter into a substantially symmetrical unit (1, 2) in relation to the optical axis (3) about which it is arranged to rotate. To reduce air turbulence when the unit (1, 2) is rotated, in front of the light admission surface (5) there is a hollow cylindrical component (11) fitted on the unit (1, 2), the axis of which substantially coincides with the optical axis (3) and the inside diameter of which corresponds at least to the diameter of the light beam (6) impinging on the light admission surface (5). The reduction in the air turbulence minimises positional errors in the deflected light beam (6'), so that, when the light beam deflector is used in an imaging device, uniform exposure and hence higher reproduction quality are attained.
