A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths ...

Images, and the devices that capture them, are my focus. I've covered cameras at PCMag for the past 13 years, which has given me a front row seat for the DSLR to mirrorless transition, the ...

Ultrafast photonics is the study of light and its interaction with matter on short timescales, typically less than a picosecond. This includes investigating processes that occur in atoms and ...

Example of far field (Fraunhofer) diffraction for a few aperture shapes. For example, if a 0.5 mm diameter circular hole is illuminated by a laser light with 0.6 μm wavelength, then Fraunhofer ...

This approach is also referred to as“diffractive imaging” because the light reflected by the sample“diffracts” freely in space towards a camera. We reconstruct the sample image from the ...
