| 摘要 | As Spatial Heterodyne Spectroscopy (SHS) technology has a narrower spectral bandpass (about 10 nm) and its applications are restricted generally, this paper proposes a tunable SHS with a grating-mirror structure to widen the application ranges of the spectrometer. The tunable structure in the spectrometer is implemented by taking a plane mirror to replace a grating in the traditional double grating SHS system, meanwhile allowing another grating to rotate. It switches measuring band to broaden measurement range and applies a small pitching angle on the plane mirror to ensure the monodromy of the recover spectra, by which the application ranges of the spectroscopy are expanded. A prototype is established to verify the feasibility of the proposed SHS. The experiment result shows that the designed SHS has the bandpass range up to about 100 nm and its spectral resolution is better than 0.29 nm. The spectrometer has a simple structure and its grating production and spectral reduction are easy to be implemented. Moreover, by increasing the rotated times of the grating and introducing methods to eliminate stray light etc, it will expand the its bandpass farther and improve the spectral resolution. 2015, Science Press.
