Abstract
Optical transducers are provided for detecting forces such as, for example rotational and transversal forces acting on them, wherein, for the purpose of detecting said forces, optical signals are transmitted through an optical path defined by optical fibers. Moreover, optical means are provided, adapted to modify the transmission of the optical signals through the optical path, as a result of forces acting on them. The resulting optical signals exiting the transducer are then used for the purpose of detecting the forces acting on the transducer.
Claims25
An optical transducer for detecting forces acting on said transducer, said transducer comprising:
- an optical path adapted to transmit optical signals therethrough;
- and
- moveable means adapted to be moved as a result of a force acting on said optical transducer so as to modify the transmission of said optical signals through said optical path as a function of the position of said moveable means with respect to said optical path.
A measuring device for measuring and/or detecting forces, comprising:
- an optical transducer for detecting forces acting on said transducer, said transducer comprising:
- an optical path adapted to transmit optical signals therethrough;
- and
- moveable means adapted to be moved as a result of a force acting on said optical transducer so as to modify the transmission of said optical signals through said optical path as a function of the position of said moveable means with respect to said optical path.
A measuring system for measuring forces, comprising:
- at least one measuring device, wherein the measuring device includes an optical transducer for detecting forces acting on said transducer, said transducer comprising an optical path adapted to transmit optical signals therethrough and moveable means adapted to be moved as a result of a force acting on said optical transducer so as to modify the transmission of said optical signals through said optical path as a function of the position of said moveable means with respect to said optical path;
- and
- at least one optical signal emitting device for introducing optical signals into said optical path and at least one optical signal receiving device for receiving optical signals exiting said optical path, said optical signal receiving device being operative to convert optical signals into electrical signals.
