PARALLEL-PROCESSING, OPTICAL DISTANCE-MEASURING DEVICE

摘要

A device is proposed for determining 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 informatio n into information on intensity, in which simultaneous or concurrent in time n signals are produced by the detector (10), each of the n signals being uniquely assigned to one o f 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.
