Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

We think of optical lasers and microwaves as functioning in distinctly different regions and with disparate modes within the broad electromagnetic spectrum. However, it doesn’t have to be that way, as ...

As optical bandwidth requirements increase, system designers are turning to “coherent” modulation schemes that can place more data on the same laser light, and lower power over long connections. A ...
