Tapping hidden visual information: An all-in-one detector for thousands of colors

Science Daily  October 20, 2022 Miniaturized computational spectrometers, which can obtain incident spectra using a combination of spectral responses and reconstruction algorithms, are essential for on-chip and implantable applications. Highly sensitive spectral measurement using a single detector allows the footprints of such spectrometers to be scaled down while achieving spectral resolution approaching that of benchtop systems. An international team of researchers (Finland, USA – Oregon State University, South Korea, UK, China) has developed a high-performance computational spectrometer based on a single van der Waals junction with an electrically tunable transport-mediated spectral response. They achieved high peak wavelength accuracy, high spectral […]
