Abstract

The invention is an opto-electronic based contactless bending angle measurement mechanism (20) characterized by comprising at least one pair of distance measuring sensors (28) which produces the distance information with respect to the signal provided by the optical receiver (282); a sensor movement mechanism in order to move said couple of distance measuring sensor (28); a main control unit which compares the distance data provided by the processor unit of the two distance measuring sensors (28) and accordingly, which provides the sensor movement mechanism to displace the distance measuring sensors (28) along the bending so that the laser rays (30) reach the work piece (40) perpendicularly and an angle measuring device which detects and measures the movement amount of said distance measuring sensors (28). The resulting angle coresponds then to the bending angle.
