Green fluorescent proteins (GFPs) in eppendorf tubes glow green because they have absorbed exitation light. Credit: Juan Carlos Fonseca Mata Green fluorescent proteins (GFPs) in eppendorf tubes glow ...

While conventional photodetectors can only measure light intensity, the light field contains much richer information. This information includes but is not limited to phase, polarization, and spectrum.

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