  • Patent number: 9614346
    Abstract: This invention provides a system and a method for measuring displacements and movements, particularly for measuring very fine displacements and very minute movements. Position, vibration and rotational/angular movements can be measured. One or more directions can be measured simultaneously. In one embodiment, the system comprises one or more measuring means at least configured to tune multiple color emissions from a laser comprising an organic laser and/or a cascaded organic laser, such that the tuned multiple color emissions of the laser are used in measurements. The system is scalable in order to support measurement across a very large space. Optionally, the system further comprises a thin film laser generating device for generating said laser, blue and green emission organic semiconductors for generating said organic laser, and laser sensors for sensing said laser where said laser sensors comprise organic laser sensors and/or cascaded organic laser sensors.
