“…Usually the WPs are made of uniaxial birefringent crystal and the splitting angle is variable due to the dispersion in birefringence [30], which would lead to interference image blurring. Fortunately, the achromatization of the traditional WP by combining two WPs of similar and opposite chromatic dispersions are proposed [39], and can be used to overcome the above drawback over a spectral region of 400 nm ~ 700 nm.…”

“…Recent progress in the Fourier transform imaging spectrometers that based on birefringent interferometers has remarkably enhanced the performance of static, compactness, and robustness, especially the capability to maintain polarization transmission accurately [21][22][23][24][25][26][27][28][29][30][31][32][33][34]. However, such spectrometers can only acquire a linerly polarized component due to the front fixed polarizer.…”

“…The OPD of the Wollaston interferometer varies along the x axis, ( , β is the apex angle of WP[30]. As can be seen, the OPD is the function of apex angle and shift x instead of field of view.…”

Three compact and static birefringent Fourier transform imaging spectropolarimeters are presented. They based on the different combinations of birefringent elements, including Savart polariscope, Wollaston prism, achromatic half-wave plate and quarter-wave plate. After acquiring several interferograms simultaneously for different polarization states with a single CCD, the spectral dependence of polarization states are recovered with Fourier transformation. The interference models are described theoretically, and the performances are demonstrated through numerical simulations and experiments. In contrast to the well-known channeled spectropolarimetry, the most important advantages are that the sampling interferograms have no channel aliasing and directly correspond to the maximum optical path difference of birefringent interferometer. That is say, they can recover the spectral variation of polarization state with the interferometer's maximum spectral resolution.

“…In order to remedy this, one solution is to widen the field-of-view, allowing a much greater system response [27][28][29]. As above mentioned, the temperature difference is very large on Mars, so it is also important that the interferometer be reasonably well compensated thermally; that is, temperature changes should not have a large effect on the optical path difference.…”

Passive optical remote sensing is one of the effective methods to measure the composition of the Martian atmosphere. A static wide field-of-view polarization Michelson interferometer is intended to be used to measure winds in the atmosphere of Mars. The highlight of the instrument is the application of a thin lens array and a polarizer array to obtain four interferograms simultaneously without moving parts; then the velocity and temperature can be deduced from the four interferograms. The thin lens array is used to divide the pupil, and this makes the optical system small and lightweight. Moreover, there is no influence on the recovered temperature and velocity when the lens array is misaligned. A fully compensation technology is applied to widen the field-of-view and fulfill achromatic and thermal compensation, and simulations show that the designed scheme responds well to theoretical expectation.

“…In 1990, there have been many studies on polarization interference spectrometers. For example, Zhang et al [3][4][5][6][7][8][9][10][11][12] proposed the stationary polarization interference imaging spectrometer in 2000, and it possesses many merits such as stationary without mechanism motions, large field of view and high throughput.…”
