Near-infrared metalens provide higher contrast in skin and blood vessel imaging due to their greater penetration ability in biological tissues, allowing for clearer visualization of vascular structures and tissue layers. Compared to traditional lenses, near-infrared metasurface lenses are significantly smaller in size, enabling the miniaturization of imaging modules, which is especially suitable for use in endoscopic surgery. This slim optical design allows endoscope probes to be thinner and more flexible, enhancing the ease of operation for physicians, reducing tissue invasiveness for patients, and improving overall surgical safety and precision.
Thermal imaging metalens modules can be used to build non-contact body temperature monitoring systems that visualize human temperature information using far-infrared light, providing real-time and intuitive images of temperature changes. Compared to single-point measurement methods, thermal imaging can simultaneously observe temperature distribution across the entire body surface area, helping medical staff quickly identify abnormal heat sources or localized inflammation. This technology is particularly suitable for hospitals, long-term care facilities, and crowded public spaces, improving temperature monitoring efficiency and reducing the risk of cross-infection.
