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.
