Abstract: The fibre optic distance sensor which uses controlled introduction of bend losses to a optical fibre includes a fibre optic line connected to a light source and a detection system, containing at least one fibre optic sensor connected in at least one place with a winding module, and outside the attachment area or in this area - a section of the fibre optic line is led out of the winding module. The process of distance measurement using the distance sensor consisting in positioning in the area of connection of at least two elements a distance sensor between elements so that the distance sensor in accordance with the invention is subject to elongation and contraction, and then a light signal from the light source is fed to the fibre optic line, and then conducted in a transmission or reflectance set-up using at least one fibre optic line so that as a result of elongation or contraction of the sensor bend losses are introduced, and the optical signal strength downstream the winding module area is measured.
