Method and device for functional testing of a fiber optic sensor and computer program product

摘要

The present disclosure relates to a method (200) for functional testing of a fiber optic sensor (110). The method (200) comprises receiving (220) optical sensor signals of the fiber optic sensor (110) in an evaluation unit (120), determining (230) a first quantity from the optical sensor signals, determining (240) whether the first magnitude within a predetermined range, determining (250) a malfunction of the fiber optic sensor (110) if the first size is outside the predetermined range, and determining (260) a second size from the optical sensor signals different from the first size when it is determined that the first magnitude is within the predetermined range, the second magnitude indicative of a parameter to be determined by the fiber optic sensor (110).
