Abstract
Metrological analysis of triangulation laser sensors for detecting distances to specular surfaces was performed. Theoretical and experimental studies have established that the measuring range distance depends on the angle of incidence of the laser beam, and the main factor that affects the measurement accuracy is the rotation of the sensor in the plane of incidence. A design of a non-contact detector of the distance to a liquid surface is proposed which provides signaling upon reaching a predetermined value. An overview of triangulation measurement systems is given.
