Technical Electrodynamics| Summary: | It is shown that in high-precision optoelectronic systems for measuring the linear displacements of objects with diffuse-reflecting surface, built on the basis of phase laser rangefinders, to ensure a given accuracy, it is necessary to compensate for the effect on the measurement of harmonic noise. Methods of compensation of this influence which are based on use of various algorithms of measurement of a phase shift proportional to distance which is defined are considered and analyzed. The disadvantages and advantages of each of the methods are evaluated, recommendations for their use are made. It is proposed to compensate for the harmonic interference of the use of electro-optical switches. References 12, figures 3. |
