High-Speed Spectral Imaging Captures Tissue’s Chemical Makeup
IRVINE, Calif., Jan. 16, 2023 — Scientists at the University of California, Irvine developed a spectral imaging technique that is poised to help researchers and industries across multiple fields, including medical and tech, quickly visualize the chemical composition of tissues and various materials. The mid-infrared (MIR) imaging technique is based on nondegenerate two-photon absorption (NTA) of temporally chirped optical MIR pulses. Called chirped-pulse NTA (CP-NTA), the technique also enables high-speed imaging,
