A Fabry-Perot sensor for measuring an inclination. The sensor is fixed on a static detected object, where a mass block is flexibly connected to a top plate, thus the line between the center of gravity of the mass block and the connecting point on the top plate is perpendicular to the horizontal plane. This creates a Fabry-Perot cavity between a reflecting surface disposed at one end of the mass block and the end of an optic fiber. When the detected object is tilted, the line between the center of gravity of the mass block and its connecting point on the top plate remains perpendicular and the F-P cavity length will have a variation in length. The change of cavity length is measured in accordance with the Fabry-Perot principle, thereby the tilting angle, which is the inclination of the detected object, of the mass block is measured.

The disclosure provides a work tool positioning system for a work machine comprising a movable work tool. The work tool positioning system comprises a work tool mounted at an end of a movable arm. At least one proximity sensor is provided for providing a proximity signal indicative of a distance between the at least one proximity sensor and an object in front of the proximity sensor. A processor is configured to receive the proximity signal and to calculate a clearance distance between a reference location on the work tool and an object in front of the proximity sensor. An alert system is provided for alerting an operator of the work machine. The processor is configured to activate one or more alerts when the clearance distance is greater than or equal to a first threshold unloading distance.
