An optoelectronic sensor for measuring the position and wear of a rail, comprising a rail mounted light source, including a laser light source with a light generating unit, optically coupled through the rail to an image unit including optical devices, one of which is oriented for horizontal, and another for the vertical components of the image of the rail, and a signal processing unit, characterized in that the node forming the illumination on the rail is made in the form of a lens that provides illumination the head of the rail in the form of a strip of laser light, the optical device is based on a charge-coupled device (CCD) equipped with an imager, for example, an anamorphic lens, at the input and connected to the signal processing unit, while the CCD sensitivity satisfies the expression
where F is the sensitivity of the CCD;
I is the light intensity of the rail;
L is the distance from the rail;
R is the reflectivity of the rail;
K is the coefficient of proportionality.
