  • 本文基于孔径分割、视场分割与通道光谱技术, 提出一种成像光谱偏振技术的新方案. 本方案在单一面阵探测器上同时获取经过不同强度调制的两对正反相干涉图, 四幅干涉图相加获取强度加倍的目标图像, 正反相干涉图相减获取纯干涉条纹, 纯干涉条纹相加减获取强度加倍的单通道干涉条纹, 对单通道干涉条纹进行傅里叶变换获取目标的光谱与偏振信息. 文中描述了方案的原理结构, 推导出了干涉强度的表达式, 并利用计算机仿真验证了方案的可行性. 为新型成像光谱偏振仪的设计和工程化应用提供了一种新思路.
    In order to obtain accurate image, spectrum and polarization state of target by the interferometric channeled spectropolarimeter, the interferogram and the image need to be separated. Although it can be achieved by digital image processing technology, heavy computations with approximation would be introduced. In the application of channeled spectropolarimetry, an inevitable crosstalk will be present between channels of the interferogram formed on the CCD. Spatial filtering in the optical path difference domain will generate a loss of spectral resolution and the distortion of the recovered spectrum. To overcome these drawbacks, a static imaging channeled spectropolarimeter based on division of aperture and field of view is presented. The aperture is divided by a polarization array, which consists of two polarizers with their transmission axes perpendicular to each other. The field of view is divided by a pair of lenses with the same focal lengths. The spectral modulation module is composed of an achromatic quarter wave plate, a retarder and a polarization array. The interference system consists of an achromatic half wave plate, a Wollaston prism, and a Savart polariscope. Two pairs of in-phase and anti-phase interferogram with different intensity modulations can be obtained simultaneously on a single detector array. The pure image of the target is acquired by the summation of the four interferograms. The background intensity is removed by the subtraction of the interferograms with in-phase and anti-phase, and the pure interference fringes can be acquired. By the summation and subtraction of the two pure interference fringes, the single channeled interference fringes corresponding to spectrum of intensity and linear polarization state can be obtained. Spectral and polarization information of the target are acquired by Fourier transform of the single channeled interference fringes. Compared with previous instruments, the described model has the significant advantage that the background intensity can be removed from the hardware of the layout, and thus avoiding the spatial filtering in the optical path difference domain. The obtained spectra have the same resolutions as those obtained from the interference system, and the distortion of the recovered spectrum can also be vanished. Since there is neither rotating part nor moving part, the system is relatively robust. In the present paper, the principle of the instrument is described, and the interference fringe intensity distribution formula is obtained and analyzed. The performance of the system is demonstrated through a numerical simulation. This work will provide an important theoretical basis and the practical instruction for designing a new type of imaging sepctropolarimeter and its engineering applications.
