Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...
Sure, a hacker could make one if he or she put their mind to it. But make one out of a webcam, some cheap diffraction grating purchased off ebay and some scrap? Surely not. [Renaud] pulls off this ...
The solution was then cast on a holographic diffraction-grating master mould to obtain free-standing silk gratings with a grating pitch of 600 grooves per millimetre, as shown in Fig. 4.
and Λ is the grating period. The efficiency has a well‐defined dependence on polarization. In particular, it is possible to obtain theoretical 100% diffraction efficiency with one linear polarization ...
For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th century, scientists realized it was both: massless particles and waves.
Scientists have unlocked a previously unseen behavior of acoustic waves, opening up new possibilities for cutting-edge ...
