描述了一种快照多光谱成像技术，其采用多个级联的双折射干涉仪来同时对多个光谱图像进行光谱滤波和解复用到单个检测器阵列上。光谱图像直接记录，而不需要反转，没有拒绝的光，因此该技术提供了高信噪比的潜力。八波段多光谱电影序列的一个例子，我们相信这是第一次这样的演示技术能够记录多光谱电影序列，而不需要计算机重建。(C)2010年美国光学学会
A snapshot multi-spectral imaging technique is described which employs multiple cascaded birefringent interferometers to simultaneously spectrally filter and demultiplex multiple spectral images onto a single detector array. Spectral images are recorded directly without the need for inversion and without rejection of light and so the technique offers the potential for high signal-to-noise ratio. An example of an eight-band multispectral movie sequence is presented; we believe this is the first such demonstration of a technique able to record multi-spectral movie sequences without the need for computer reconstruction.
