High Precision Angular and Linear Measurements Using Universal Opto-Electronic Measuring Modules in Distributed Measuring Systems

摘要

Large or long objects require measuring systems as a combination of more than one measuring instrument. In this case, the combination of instruments consists of one central module and several measuring modules. The measuring modules make the preliminary computation of measuring information and translate it to the central module for final computation of measuring parameters. The central module also makes statistics of measuring and archive information. Some tasks require noncontact measurement of angular and linear coordinates of objects or places. The optoelectronic measuring devices (0EMD) are ideal for these purposes. These devices also have other advantages such as high precision and adaptability. One and two coordinates high precision modules based on matrix and linear CCD or CMOS photo sensors are described. In this article variants of the distributed measuring systems are described. The basic attention is given to the description of the unified optoelectronic modules for measurement of angular and linear coordinates. Basic parameters and application examples of measuring modules are presented.
