传统光学器件色散重建方法:

缺少准直光学器件,导致色散的波长依赖,非线性。
This is due to the absence of collimating optics (common in professional hyperspectral imagers)
and the resulting wavelength-dependent, nonlinear refractive distortion created by the prism

缺少信号调制和约束条件,优化难度大
without relying on spectral signatures from a coded aperture.
