    Abstract: A fiber laser device includes a laser pump for irradiating a laser beam, an optical component, an optical fiber and an optical sensor. The optical component has a first and a second output end, wherein a portion of the laser beam is output from the first output end and another portion of the laser beam is output from the second output end. The optical fiber including a core and a cladding layer is optically coupled between the laser pump and the optical component. A inclined angle θ of the first output end satisfies the following relations that θNA/2≦θ≦θNA, and θNA=sin−1(NA·ncladding/ncore), where NA is numerical aperture of optical fiber, ncore is refractive index of the core, and ncladding is refractive index of the cladding layer. The optical sensor is disposed at a light-transmission path of the laser beam reflected by the first output end.

    Abstract: A reading circuit of a gyroscope is provided. The reading circuit includes a driving unit, a high pass filter, a signal processing unit, and a low pass filter. The driving unit generates a resonance signal for a resonator of the gyroscope and generates a demodulation signal for the signal processing unit. The signal processing unit provides a modulation signal to a Coriolis accelerometer of the gyroscope. An input terminal of the high pass filter receives an output signal of the Coriolis accelerometer. The signal processing unit processes and demodulates an output of the high pass filter according to the demodulation signal and outputs a demodulation result to the low pass filter.
