摘要： PROBLEM TO BE SOLVED: To accomplish a variable gain trans-impedance amplifier that can effectively respond to radiation events, unit to unit loss variation, and optical loss associated with end of life, without significantly degrading the amplifier bandwidth.
SOLUTION: The present invention relates to a trans-impedance amplifier with gain control for a fiber optic rotation rate sensor. A variable gain amplifier has gain control based on keeping the amplifier output above a certain level. A gain control circuit includes a control device connected to ground and the amplifier feedback network, The input to the gain control circuit can be the amplifier output that has been filtered, or the input can be from an external circuit or microcontroller.

摘要： PROBLEM TO BE SOLVED: To provide systems and methods for performing vibration error suppression in an optical fiber gyrosensor.
SOLUTION: An example system includes a light source, a sensing loop assembly, a photodetector, and a processing component. The light source generates a light signal that is then modulated by the sensing loop assembly and applied to an optical fiber coil in the assembly. The photo detector receives a modulated light signal that is the output of the sensing loop assembly (coil) and generates an analog signal. The processing component converts the generated analog signal into a modulated digital signal, determines an average of the modulated digital signal, determines an intensity modulation amplitude from the determined average of the modulated digital signal, and re-scales the modulated digital phase signal from the determined intensity modulation amplitude.

摘要： PROBLEM TO BE SOLVED: To provide a method for calibrating an optical fiber gyroscope.
SOLUTION: This method is for calibrating an optical fiber gyroscope. A first part and a second part of light from a first light source pass through an optical fiber line, and propagate in a first direction and in a second direction respectively. A first voltage which produces a predetermined phase shift between the first part and the second part of the light from the first light source is computed. A first part and a second part of light from a second light source pass through an optical fiber line, and propagate in the first direction and in the second direction respectively. A second voltage which produces a predetermined phase shift between the first part and the second part of the light from the second light source is computed. Then the difference between the first voltage and the second voltage is computed.

摘要： PROBLEM TO BE SOLVED: To provide a system and a method for generating a clock highly tunable for a proper frequency, and a high-speed clock for a photodetector sampling converter requiring no radiation resistant type high-speed device difficult to practically provide. SOLUTION: The clock system for an optical fiber gyroscope includes the clock highly tunable for bias modulation, and the separate asynchronous high-speed clock for sampling a photodetector. This clock system/method attains both a purpose as to tuning possibility of a bias modulation clock and a purpose as to quickness of the sampling clock, while using a radiation resistant type electronic component of low performance easy to be used, by not using two derivatives of the same clock but by separating the two clocks.
