optical perturbation

Optical perturbation refers to any disturbance or alteration in the characteristics of light as it propagates through or interacts with a medium. This perturbation can include changes in the direction, intensity, polarization, or phase of light due to factors such as scattering, absorption, refraction, or diffraction within the medium. Optical perturbation is a fundamental concept in fields such as optics, photonics, and optical communications, where understanding and controlling how light behaves in various mediums is crucial.
