摘要： An optical gyroscope and a method for measuring an angular velocity of rotation are described. A closed-path optical cavity is configured for receiving at least a first optical signal circulating as at least one cavity mode of pre-determined orientation (inside the optical cavity. An extractor in optical communication with the optical cavity is configured for extracting a fraction of at least the circulating first optical signal from the optical cavity, wherein an amplitude of the extracted fraction increases when a resonance condition for the optical cavity in optical communication with the extractor is approached. A readout channel included in the optical gyroscope comprises an interferometric device adapted to spectrally modify the extracted fraction so as to produce a spectral Vernier effect. A difference between free spectral ranges of the interferometric device and the optical cavity is larger than the associated spectral widths. Readout detectors are included in the readout channel for detecting optical power levels of the spectrally modified optical signal, based on which the angular velocity is determined.

摘要： Embodiments relate to a sensor structure for an acoustical pressure sensor and an opto-mechanical sensor and system that may be used for detecting acoustical pressure waves. Embodiments of a sensor structure for an acoustical pressure sensor include an optical waveguide closed-loop resonator and a plurality of sensor elements. The individual sensor elements of the plurality of sensor elements are configured to be affected by an acoustical pressure wave such that a physical property of the individual sensor element is changed. The optical waveguide closed-loop resonator is arranged at the plurality of sensor elements and associated with each of the individual sensor elements such that a resonance frequency of the optical waveguide closed-loop resonator is shifted due to the affected physical properties of all individual sensor elements. The sensor structure provides a high sensitivity from each sensor element, which is advantageous in e.g. ultrasonic imaging, such as photo-acoustic imaging where the signals typically are low.
