Existing static dispersive and interference imaging spectrometers use fixed spectral resolution to obtain a fixed spectral data cube. To satisfy a variety of application requirements, the spectral range must be large and the resolution must be fine. This will result in a huge data and reducing the S/N ratio of the instruments. To solve these problems, a novel birefringent Fourier transform imaging spectrometer with spectral zooming capability is proposed. Operating concept, theory and experimental demonstration are presented to validate that the designed setup has wide spectral zooming capability. It can adapt to different applications, significantly reduce the size of the imaging spectral data for capturing, saving and processing. This will effectively improve the system performance.
