System for precise balancing and controlled unbalancing of fiber-optic interferometersSirotić, Irvin (Avtor) Đonlagić, Denis (Avtor) electrical measurementsoptical instrumentsinterferometersfiber interferometersoptical path differencesensor systemsA system for accurate balancing and controlled unbalancing of the optical path difference in all-fiber optical interferometers is described. Interferometers with various arm lengths (1-30m) and with initial optical pathdifferences of as much as 1 cm have been successfully balanced within a 5 ▫$mu$▫m range. In addition, the proposed system allows for controlled unbalancing of arbitrary all-fiber optical interferometers with a precision better than 5 ▫$mu$▫m.20022012-06-01 13:04:24Neznano27868UDK: 681.586:531.715COBISS_ID: 7396886ISSN pri članku: 0003-6935NUK URN: URN:SI:UM:DK:ZQONGL7Fsl
