Snapshot Spectrometer Enhanced by Randomly-Textured Lithium Niobate
A new integrated "snapshot spectroscopy" system developed in China has shown 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.
Conventional spectrometers rely on diffractive optics to separate incoming light into its constituent wavelengths, making them large, expensive, and inefficient for rapid image acquisition.
Spectroscopy is crucial to analysis of all kinds of objects in science and engineering, from studying the radiation emitted by stars to identifying potential food contaminants.
- Astronomical imaging
- Materials analysis
Other applications are also possible with this new system.
Author's summary: New snapshot spectroscopy system outperforms existing ones.
