New surface-mount optical sensors increase vertical headroom, enabling more flexible encoder and position-sensing designs ...

Most CES tech is still on the horizon, but these products are already real, priced and (mostly) ready to ship.

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, or a ...

Fibre optics and optical communications is the use of thin strands of glass for sending information encoded into light over long distances. Total internal reflection prevents light inserted into one ...
