Researchers fabricated a 1200 lines/mm gold-coated pulse compression grating with 91.4 percent average diffraction efficiency ...

If you are like me then you might not always get caught up in some of the super technical aspects of photography. One aspect of photography I recently investigated was the loss of sharpness caused by ...

An experimental graphene optical system uses red, green and blue light challenges, transformer-assisted image analysis and binary codes to create programmable hardware-based authentication responses.

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 ...

Spectrometers are crucial scientific instruments in various research fields and have consistently served as indispensable tools for foundational research. However, the unwieldy size of conventional ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

Single-crystal diffraction was invented 100 years ago by Max von Laue. It has since become a workhorse technique for chemists to determine the structures of organometallic complexes and other ...

Diffraction is something that can rob your images of sharpness, and as such, it is important to have a functional understanding of what it is and how to avoid it. This excellent video explains what ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...
