DOIAbstract
A new approach called agile interferometry is introduced to attain interferometric information with high sensitivity and scenario-based intelligence. Compared to traditional interferometric techniques, the proposed method thrives on dynamic control of the reference signal strength and detector integration time for efficient interferometric detection with high signal-to-noise ratio and significantly improved detected signal dynamic range capabilities. Theoretical analysis is presented with the operational methodology of the new approach. A high-speed optical attenuator is required in the interferometer reference arm to implement the proposed agile interferometer. © 2004 Elsevier B.V. All rights reserved
