A new integrated system developed in China has achieved a significant boost in snapshot spectroscopy, outperforming existing astronomical spectrometers.
The system utilizes randomly textured lithium niobate, enabling the determination of spectral and spatial composition of light with higher precision than other systems.
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, making them large, expensive, and inefficient for rapid image acquisition.
Author's summary: New snapshot spectroscopy system outperforms existing ones.
