Randomly-textured lithium niobate gives snapshot spectrometer a boost – Physics World

Snapshot Spectrometer Enhanced by Randomly-Textured Lithium Niobate

A new integrated system developed in China has improved the precision of snapshot spectroscopy, outperforming existing astronomical spectrometers.

The system utilizes randomly textured lithium niobate, enabling the determination of spectral and spatial composition of light with high precision.

Spectroscopy is crucial to analysis of all kinds of objects in science and engineering.

Conventional spectrometers rely on diffractive optics, making them large, expensive, and inefficient for rapid image acquisition.

Author's summary: New snapshot spectroscopy system outperforms existing ones.
