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

In many lighting applications, measuring the relative intensity of two light sources is more important than measuring their individual intensity. This ensures that two light sources shine with the ...

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 ...

Measuring the average intensity of the visible radiation emitted from an LED is a critical issue, not just for developers of electro-optical instrumentation and photonics measuring devices, but also ...
