Adjustable spectrum correction system and method

Abstract

The invention belongs to the technical field of interferometer systems, and particularly relates to an adjustable spectrum correction system and method. The system comprises a swing device, a swing driving device, a control circuit device and a high-frequency working device. The method comprises the following steps: S1, inputting triangular wave current, and judging whether an interference peak is centered or not; if not, turning to the step S2; s2, starting bias adjustment, and judging whether the first data separator is A or B; s3, if the data separator is A, determining the data separator as a rising edge, and if the swing arm deviates leftwards, increasing a bias parameter; if the swing arm deviates rightwards, the bias voltage parameter is reduced; s4, if the data separator is B, determining the data separator as a falling edge; if the swing arm deviates leftwards, the bias voltage parameter is reduced; if the swing arm deviates rightwards, the bias voltage parameter is increased; and S5, when the position of the swing arm after deviation rectification is in the middle, the deviation rectification process is completed. The device has the advantages that environment vibration can be counteracted, and the magnitude of current can be adjusted according to the inclined ground, so that the swing arm is centered.

Description

technical field [0001] The invention belongs to the technical field of interferometer systems, and in particular relates to an adjustable spectrum correction system and method. Background technique [0002] At present, in the interferometer system, external vibration or ground tilt will cause abnormalities in the swinging process of the swing arm, which will lead to spectral anomalies and seriously affect the spectral performance. [0003] Therefore, it is very necessary to design an adjustable spectrum correction system and method that can not only offset the environmental vibration, but also adjust the magnitude of the current to make the swing arm centered. [0004] For example, the application number is CN201320374721.X, a kind of miniature Fourier transform spectrometer described in the Chinese patent literature, including a light source, an interference system, the interference system includes a first beam splitter, a moving mirror, a fixed mirror, the light emitted by...
