摘要：The paper deals with an active triangulation technique of non-contact optical measurement of 3D properties. The basic features of the method - principle, advantages and disadvantages - are described first. But the main part of the paper is concerned with the impossibility of using the basic principle of the method for measured objects, which are covered by a layer of transparent material of unknown thickness. Most often it is a layer of oil for the preservation of metal products. This layer distorts the measured value due to the light refraction. In this work, a method of eliminating this distortion based on the use of two sensors is proposed. Experimental verification of this proposal is also presented.
