Description:

In lasermike (laser measuring scanner) the measurement information is converted to become time-dependent by scanning. An object to be measured is scanned transversely by a laser beam waist. An angular scanning is transformed into linear by scan lens and the detector output signal is of the form of shadow of an object. Assuming constant scan velocity, the shadow time is the measure of the size of an objedt. A quick scanning of a beam makes lasermikes indispensable in all kinds of dynamic operations. There are four main areas of application: read/write/ display, technology, medicine nad measurement. In the presented paper the scanned laser beam is split into two mutually orthogonal beams giving information not only about the dimension, but also about the position and the form of an object. The reference standard introduces within the measuring area enables the simultaneous calibration of the system. We used the simple polygon-mirror-based scanner driven by synchronous motor. The system operates in the 10x10 mm range with resolution 0.1 μm. and Obsahuje seznam literatury
