摘要

研究表明，在基于相位激光测距仪的高精度漫反射面物体线位移光电测量系统中，为了保证给定的精度，有必要补偿谐波噪声对测量的影响。考虑并分析了基于使用与所定义的距离成比例的相移的各种测量算法来补偿这种影响的方法。评估了每种方法的缺点和优点，并提出了使用建议。提出了用电光开关来补偿谐波干扰的方法。参考文献12，图3。

METHODS FOR IMPROVING THE NOISE IMMUNITY OF HIGH-PRECISION LASER OPTOELECTRONIC SYSTEMS FOR MEASURING LINEAR DISPLACEMENTS

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.
