Researchers create low-cost, AI-powered device to measure optical spectra

A team of researchers at the UCLA Samueli School of Engineering has demonstrated a new approach to an old problem: measuring spectra of light, also known as spectroscopy. By leveraging scalable, cost-effective nano-fabrication techniques, as well as AI-driven algorithms, they built and tested a system that is more compact than conventional spectrometers, while also offering additional design advantages.
