Engineers who work with LEDs, laser diodes, and other types of lasers need to know about the radiation produced at various wavelengths. These optical sources may look monochromatic to the human eye, ...

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

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...
