Understanding Interference in Optical Engineering

Learn about wave interference in optical engineering, where overlapping waves result in amplitude addition. Explore the concept of interference between two waves and how it affects power density. Discover conditions for maximum and minimum interference and examples illustrating interference phenomena.

  2. Interference • This can occur when 2 or more waves overlap each other in space. • Assume that 2 waves have the same frequency. • The interference results in an addition of wave amplitudes.

  3. Interference • Two wave interference: the resulting field becomes

  4. Interference • Power density, PA

  5. Interference

  6. Interference • If lights behave without interference, we would expect where E1 and E2 are orthogonal. • If there is an interference, it is clearly seen that the term is the term for “interference”.

  7. Interference • PA is max for 1 - 2= 0, 2, …, 2N • PA is min for 1 - 2= , 3, …, (2N+1) • Therefore,
