Snapshot Spectrometer Enhanced by Randomly-Textured Lithium Niobate
A new integrated "snapshot spectroscopy" system, developed in China, offers improved precision in determining the spectral and spatial composition of light from an object.
This compact system outperforms existing astronomical spectrometers, using randomly textured lithium niobate to achieve its enhanced capabilities.
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.
- Conventional spectrometers rely on diffractive optics to separate incoming light into its constituent wavelengths.
- This approach makes them inherently large, expensive, and inefficient at rapid image acquisition.
The new system has been used for astronomical imaging and materials analysis, with its developers suggesting other applications are possible.
Author's summary: New snapshot spectroscopy system outperforms existing spectrometers.
