Abstract: To improve the measurement precision of the optical encoder working at various speeds, an adaptive high-precision measurement framework is designed based on deep reinforcement learning (DRL) ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

Everyone who ever took a photo knows the problem: if you want a detailed image, you need a lot of light. In microscopy, however, too much light is often harmful to the sample—for example, when imaging ...

Optical tweezers (or optical traps) are devices that use a laser to trap a nanometre-to-micrometre-sized dielectric object in place. Optical tweezers are used for performing single molecule force and ...

If you aren't willing to haul around a heavy SLR or mirrorless camera but still want something better than a smartphone, a compact model might be the way to go. These are the best point-and-shoot ...
