Opto-isolator - Wikipedia

An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators withstand input-to-output voltages up to 10 kV and voltage transients with speeds up to 2… WebNov 14, 2024 · In fact, the coupler and the boundary between two dielectric are represented by the same transfer matrix. The subtle difference is in the phase factor of the reflection coefficient. In a boundary between two dielectrics, there is a phase shift when the plane wave is reflected from the dense media. eric bernstein san antonio texas
