Area of Science:

  • Physics
  • Materials Science
  • Acousto-optics

Background:

  • The acousto-optic technique evaluates coated substrates by analyzing the phase of reflected beams.
  • Previous methods relied on numerical simulations, which can be computationally intensive.

Purpose of the Study:

  • To develop a fully analytical model for acousto-optic evaluation of thin coatings.
  • To provide a transparent expression for phase shift and explore its applications in non-destructive testing.

Main Methods:

  • Application of normal-mode theory to model the phase shift in acousto-optic evaluation.
  • Analytical derivation of the phase shift between incident and reflected fields.

Main Results:

  • Reproduced known numerical results regarding phase dependency on coating parameters.
