DEVICE FOR MEASUREMENT OF LINEAR AND ANGULAR DISPLACEMENTS BY OPTOELECTRONIC RASTER TRANSDUCERS

摘要

The apparatus is used in metal processing machines, industrial robots, and coordinate measurement machines, and has improved noise resistance. The apparatus consists of an optoelectronic raster scanner (1), whose two outputs are connected to two inputs of an electronic interpolator (2), whose two outputs are in turn connected to the inputs of cumulative counter (5). The two outputs of optoelectronic scanner (1) are connected to the inputs of a two-channel analogue multiplexer (3), whose output is connected to analogue-to-digital converter (4), whose outputs are in turn connected to microprocessor (6). The outputs of cumulative counter (5) are also connected to system (6).
