    摘要： A device for spotwise imaging printing surfaces includes a laser light source producing at least one laser beam movable relative to a printing surface, the laser beam defining an image spot on the printing surface, the laser beam having a laser power. A laser control varies the laser power or an exposure time as a function of a distance of the laser light source from the image spot.

    摘要： A device for recording images on a printing form, including an array of light sources and imaging optics for generating (n×m) imaging spots on a printing form, which is distinguished by the array of light sources including an array of mutually independently controllable VCSEL light sources. One specific imaging spot may be formed on the printing form by combining the light emitted by a subarray of the VCSEL light sources. Due to the advantageous beam properties of VCSEL light sources, such as the small divergence and negligible astigmatism, the device for recording images on printing forms is especially advantageous for use in a printing-form imaging unit or in a print unit.

    摘要： A device determines the positional deviation of n points (P) from their reference positions using a source of electromagnetic radiation (1), imaging optics (2, 4, 9), and a photosensitive detector (10), which converts the positional information into information on intensity. Simultaneous or concurrent in time n signals are produced by the detector (10), each of the n signals being uniquely assigned to one of the reflection points (P). The generated signals can be used to control an autofocusing device or to control the intensity of light sources in devices for imaging printing forms.
