Researchers from the Chinese Academy of Science developed an endoscope capable of acquiring 3D visible light and near-infrared fluorescence images at the same time. The optical design combined high-resolution 3D imaging capabilities with the ability of the mantis shrimp to simultaneously detect multiple wavelengths of light.
The endoscope uses a stereoscopic design to achieve 3D imaging while a sensor, inspired by the compound eyes of mantis shrimp, not only detects multispectral information but also recognizes polarized light. The sensor features pixels with different spectral and polarization responses, detecting multiple parts of the electromagnetic spectrum.
Different concentrations of the fluorescent reagent indocyanine green….
