Snapshot Multispectral Polarization Imaging
Abstract
- A new filter array and a demosaicking method for snapshot multispectral polarization imaging are proposed. A snapshot image can be obtained by attaching the proposed filter array to a monochrome camera sensor; however, each pixel value of a captured grayscale image has a different meaning depending on filter sensitivity. Therefore, we propose not only a filter array but also a demosaicking method for recovering multispectral polarization image.

Multispectral polarization filter array based on photonic crystal
- The multispectral polarization filter array is developed by altering the wave structure of the photonic crystal at each pixel. In addition, we propose a demosaicking method for multispectral polarization images by considering snapshot imaging as a linear model. From the results, the proposed imaging system achieved a simple device (using only a multilayered structure film with a monochrome camera), simple demosaicking (using only one matrix multiplication), and wide spectrum recovery including visible wavelength (420-720 nm at 10 nm, 31 bands).
