Abstract: An apparatus for optically projecting pixel-based image information onto a light-sensitive material has an image-generating device, an optical projection device, and a device for laterally offsetting the projected image of the image-generating device to produce a plurality of mutually offset partial images in the image plane. The offsetting device has two optical elements arranged in sequence in the light path of the projection. The projected partial images are offset relative to each other by tilting one or both of the optical elements.

Abstract: A device and a method is proposed for writing on imaging material (3) with a radiation source (1) producing an electromagnetic radiation having a wavelength suitable for recording image information on the imaging material (3). The radiation produced by the radiation source (1) can be modulated with a waveguide which is integrated in a substrate material (49) and operates as a modulator (2). A modulation signal containing the image information can be received at an input (9) of the modulator (2). According to the invention, a compensator (6, 12) compensates a modulation error which occurs during modulation of the radiation.
