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 ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level ...

Feb. 19, 2025 — Acting in the right place at the right time is the key to effective medical treatment with minimal side effects. However, this feat remains difficult to achieve. Biologists and ...

In addition, pearls may be subjected to routine processes such as bleaching, maeshori (luster enhancement), and optical brightening that can improve their appearances. GIA has developed novel ...

Researchers at North Carolina State University have demonstrated a new technique that uses light to tune the optical properties of quantum dots – making the process faster, more energy-efficient ...
