Paper Abstract

Investigation and comparison of modeling and experimental results for the two-fiber reflection non contact displacement sensor are presented. The main aim of the research carried out here is to compare the two light emitting fiber constants obtained in the experiment and those obtained in the modeling process and set their values for the super light diode (SLD) and laser diode (LD) type sources. In the research paper the constants k and m (describing the distribution of the light emitting source beam intensity) values obtained, alongside with which a rather good match of the experiment and modeling results was obtained. In addition, the work presents some comparisons with the beam waist calculations in which the beam waist depends on the light wavelength &lgr;. The results of research have shown that it is possible to calculate the characteristics of fiber sensors precisely enough by means of modeling. The results obtained were used in the new compensation type two-fiber optopairs sensor.
