Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...
Diffraction gratings are periodic optical structures that disperse incident light into constituent wavelengths by interference. They form a cornerstone of modern optical instrumentation, underpinning ...
Diffraction gratings separate different wavelengths of light using a periodic pattern embedded in the grating. The diffraction pattern can affect the amplitude and/or phase of the incident light as ...
