Sensing part presence in machines, in fixtures, and on conveyors is an important component of industrial automation. Error-proofing assembly and controlling sequence based on presence or absence of a ...

The amplifiers have a 0 to >200-mm sensing range, depending on the optical fibers used. Operating distance can be adjusted between 20 and 200 mm with a 12-turn potentiometer with an illuminated scale.

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.230019 discusses exceptional-point-enhanced sensitivity – a new paradigm for high-sensitivity fiber sensors. The sensitivity of a ...

For Part 1, click here. High-speed optical communications applications have some high-level transimpedance-amplifier (TIA) circuit similarities with laser rangefinders (LRFs) and LiDAR. However, there ...
