| Abstract(in English) | Compressed spectral imaging with Spectrally-varying PSFs is a technique acquiring 3D spectral data cube based on compressed sensing theory, which compresses and acquires spectral data cube on a 2D image sensor using a meta-lens with a PSF that depends on the spectrum. The con?guration of this technique is simply to replace the lens of an ordinary digital camera with a meta-lens, so it can be easily implemented in various types of cameras. Recently, monochrome sensors with extremely broadband sensitivity have been developed, and it is expected that a wider range of spectral images can be acquired by using such sensors. On the other hand, this technique has so far been evaluated only for color sensors, and its in?uence on monochrome sensors is not clear. Therefore, this paper quantitatively compares the di?erences in performance of this technique when implemented with a color sensor and a monochrome sensor through simulation experiments. |
