Embodiment Construction

[0070] The present invention will be described in detail below in conjunction with specific examples and accompanying drawings.

[0071] The invention provides a measuring device, such as figure 1 As shown, it includes an analog acquisition setting unit, an analog acquisition unit, an acquisition data filtering and drawing unit, a curve parameter dynamic measurement setting unit, a curve parameter dynamic measurement and calculation unit, a curve parameter display unit and a curve parameter storage unit.

[0072] The analog quantity acquisition setting unit is used to set the sampling frequency of analog quantity acquisition, the sampling time of each sampling and the cutoff frequency of low-pass filtering. In this example, the frequency f of each channel of analog acquisition can be set to 5MHz, and the time of each sampling t 1 is 100ms, then the dynamically allocated memory size t 1 *f*1024*1024 / 1000 is the storage space of 524288 float types; the cut-off frequency of th...

Description

technical field [0001] The invention relates to a device and method for measuring dynamic parameters of a gyroscope circuit, belonging to the technical field of optical gyroscopes. Background technique [0002] The optical resonant cavity is an important component of the optical gyroscope. It is a resonant system with distributed parameters. The resonant cavity is a cavity that provides light energy feedback for the light wave to reflect back and forth. When the light wave propagates in the cavity, it is caused by various physical factors. Optical loss, the optical loss of the resonator is composed of diffraction loss and lens transmission loss. The optical loss value is the most important parameter of the resonator, which can be calculated by measuring the resonator curve output by the resonator control circuit. The production technician can change the resonator curve and then change the optical loss value through debugging until it meets the requirements. [0003] The tra...
