Optical system design for long-range beam detectors and industrial sensing applications, from component selection to mechanical alignment.
Beam smoke detectors detect smoke by monitoring a reduction in received infrared light across large spaces such as warehouses and halls. In the reflective arrangement shown here, the transmitter and receiver share one unit, while a reflector returns the light across the monitored space.
My most extensive optical design work involved long-range beam smoke detectors (Mavili Elektronik, Teknim Elektronik).
This work included lens selection, focal-position determination, lens-holder design, transmitter–receiver spacing, reflector selection, and detection-range and angular-tolerance testing.
