Annotation
The influence of temperature on the error of incremental optoelectronic encoders of linear displacements based on raster structures, is considered. Basic principles of optoelectronic encoders of linear displacements are described. The performed theoretical analysis of additional error because of ambient temperature fluctuations demonstrates that the greatest influence is exerted by changes in the linear dimensions of the raster structures caused by linear expansion of the raster material. Results of experimental studies of the error of the LIR-14 encoder caused by changes in the ambient temperature are presented, and an estimate is given of the degree of influence of the error components due to this phenomenon.
