Developed at the Chinese Academy of Sciences (CAS; Shenyang, China), Tianjin University of Technology (China), and other institutions, the novel endoscope achieves coincident real-time imaging of 3D stereoscopic colour and NIR fluorescence images. The device consists of a broadband binocular optical system, a multiband sensor, and an optical relay system that projects the two sub-images from the broadband binocular optical system onto the multiband sensor, which detects spectral and polarization responses along the electromagnetic spectrum. The study was published in the January 2021 issue of Optics Express.
