An international collaboration of researchers developed two new complementary approaches for versatile but precise light intensity measurements in fluorescence imaging systems. Accurate measurements ...

Deciphering the composite information within a light field through a single photodetector, without optical and mechanical structures, is challenging. The difficulty lies in extracting ...

Light has the characteristics of both a wave and a particle. Figure 1 shows the wavelengths of red and blue light. The distance between the peaks of the wave is measured in nanometers (nm). As that ...

Optical spectrometers are instruments with a wide variety of uses. By measuring the intensity of light across different wavelengths, they can be used to image tissues or measure the chemical ...

Cathodoluminescence (CL) microscopy is a highly effective and respected microanalysis tool in geosciences. This tool works by analyzing the light emitted by a mineral or gemstone, which is excited by ...

Unlike existing photodetectors that construct and integrate wavelength- and/or polarization-sensitive elements in space or time to improve the detection ability (range and sensitivity), this ...
