Development of a laser beam to the line in measuring systems

Abstract

Abstract The way of laser radiation focusing on a reception matrix when carrying out measuring works applying a narrowly targeted beam is shown in this article. For example, centering the shaft (reduction to coaxiality) pump units allows preventing emergence of vibration. It is destructive for bearings. The optical scheme consists of several parallels and a photosensitive matrix of glass cylinders. We theoretically prove the possibility of using a system optically of transparent cylinders with the calculated indexes of refraction, including diameters for development of a dot laser beam to the line. At the same time the ratio “the power of a beam/power of hindrances” of a laser beam when receiving the line in close proximity to a reception matrix increases from 10-100 times. This depends on the distance between a matrix and a source of laser radiation. It allows using lasers of the 1 class with power no more than 1 mW. For the purpose of confirmation of feasibility of the developed design, experimental measurements are carried out.
