A new integrated "snapshot spectroscopy" system developed in China offers improved precision in determining the spectral and spatial composition of light from an object.
The system utilizes randomly textured lithium niobate, outperforming existing astronomical spectrometers, including those used on telescopes, which rely on diffractive optics to separate incoming light into its constituent wavelengths.
The compact system has potential applications in various fields, including astronomical imaging and materials analysis, and could be used to study the radiation emitted by stars or identify potential food contaminants.
Spectroscopy is crucial to the analysis of all kinds of objects in science and engineering.
