DEVICE TO MEASURE ANGULAR AND LINEAR COORDINATES OF OBJECT Russian patent published in 2014 - IPC G01B11/26 G01B11/00 

FIELD: instrumentation.

SUBSTANCE: in a device to measure linear and angular coordinates of an object comprising an illuminator, a lens with a photodetector array connected to a data processing unit and set in the plane conjugated with the object, and a leading mark set on the object, the novelty consists in the fact that the leading mark is fitted by an illuminator switching on a light source, a condenser and a diffuser which are installed along the beam path, and two sighting elements forming ring and spot structures and spreaded along the optic axis, an optic path compensator is installed after the second structure along the beam path, the lens is made with variable focal length.

EFFECT: one-channel double-coordinate device to measure linear and angular coordinates of an object works in a wide range of distances with high accuracy and variable measurement range.
