The S onix is a new and ultra-compact surface metrology system that addresses the increasing need for outright speed (high-throughput) for 3D optical profiling for in-line process measurement and ...

Aging degradation and seismic damage of civil infrastructure pose a serious problem for society. One promising technology for monitoring the condition of structures is optical fiber sensing. By ...

Researchers have developed a fast and accurate flexible tactile optical sensor capable of reading Braille. The technology could enable smart readers that convert Braille to speech or text, helping to ...

Avago Technologies has announced a series of small form factor (SFF) optical mouse sensors with an integrated chip-on-board (COB) LED illuminated optical navigation system that is the thinnest in the ...

In 1978, Dr Kenneth Hill, a Canadian physicist, first demonstrated the Fiber Bragg grating (FBG), an optical sensor able to reflect narrow wavelengths of light. During the 1980s, the technology was ...
