To overcome the hardware limitations of conventional spectrometers and hyperspectral imagers a team of researchers in the US (Purdue University, AFRL) has developed a spectral information processing scheme in which light transport through an Anderson-localized medium serves as an entropy source for compressive sampling directly in the frequency domain. As implied by the “lustrous” reflection originating from the exquisite multilayered nanostructures, a pearl (or mother-of-pearl) allows us to exploit the spatial and spectral intensity fluctuations originating from strong light localization for extracting salient spectral information with a compact and thin form factor. The research can offer an alternative for spectral information processing by hybridizing digital and physical properties at a material level…read more. TECHNICAL ARTICLE
