3Optical tweezers — (originally called single beam gradient force trap ) are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch… …
4Optical character recognition — Optical character recognition, usually abbreviated to OCR, is the mechanical or electronic translation of scanned images of handwritten, typewritten or printed text into machine encoded text. It is widely used to convert books and documents into… …
5Optical fiber connector — An optical fiber connector terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so that light can pass. Better connectors lose… …
6Optical resolution — This article is about optical resolution in optics. For the method of separating enantiomers in chemistry, see Chiral resolution. Optical resolution describes the ability of an imaging system to resolve detail in the object that is being imaged.… …
