A research team revealed how deeply drone-mounted optical sensors can detect maize canopy layers using UAV hyperspectral data ...

RECENT measurements by Granit 1 on the electrical response of individual receptors in the retinæ, of various animals—frog, rat, cat, snake, etc.—have shown that the spectral sensitivity of the cones ...

Optical-resolution photoacoustic microscopy is an up-and-coming biomedical imaging technique for studying a broad range of diseases, such as cancer, diabetes and stroke. But its insufficient ...

Laser spectroscopy is a powerful tool for atmospheric gas analysis, yet traditional methods face challenges due to atmospheric turbulence and significant energy loss. While dual-comb spectroscopy ...

A research team has introduced a novel spectral method for monitoring critical nutrient elements in vegetation within karst wetlands—environments ...

A British-Chinese research group has created a new framework to assess the performance and efficiency limits of photovoltaic-thermal solar panels. They say that the improvement of spectral-splitting ...
