Multi-dimension complex calibrating method of fiber optic spectrometer

The invention discloses a multi-dimension complex calibrating method of a fiber optic spectrometer. The calibrating method comprises the steps of multi-dimension wavelength calibration and multi-dimension amplitude calibration, wherein multi-dimension calibration is executed to the wavelength and the amplitude by introducing temperature factors so that stability of the spectrometer is increased at high and low temperature; in the calibrating method, various operating factors of CCD (Charge Coupled Device) are fully considered, and multi-dimension complex calibration is executed to the fiber optic spectrometer in combination with multiple dimensional calibration factors of space, time, temperature and light intensity to ensure reliability of test results.
