Another related type is the reflective opto transducer, which operates by detecting reflected light from a surface rather than an interrupted beam. However, slotted opto sensors are particularly effective when a clear distinction between an object and the background is required as it passes through a defined path.
While the basic principle of operation is simple, the underlying physics involves concepts from optical physics and optoelectronics.Transducer – principle of operation and examples ... Optoelectronic transducer devices, in general, deal with the interaction between light and electronic components. This field involves the study, design, and manufacture of hardware devices that can convert electrical signals into photon signals and vice versa.
