Optical techniques are methods that use light to probe or control matter. One prominent example is optical spectroscopy, which includes such methods as pump–probe spectroscopy, Raman spectroscopy and ...

Here’s something fun from [Chad Kapper] over on HackMakeMod: Escape Room Lockbox with the Cheap Yellow Display. You may have heard of the “cheap yellow display” (CYD), so-called due to the board’s ...

Solar background and multiple scattering degrade the profiling depth and ocean-color parameter retrieval of ocean LiDAR. Our anti-interference circularly polarized LiDAR effectively suppresses these ...

Our lens reviews offer detailed information on sharpness, distortion, bokeh, and all the other important factors that go into making a lens great. Our reviews give you all the information you need to ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, ...
