Frustrated total internal reflection, or FTIR, is a phenomenon that occurs when electromagnetic waves reflected within an optical medium (with a lower index of refraction) are interrupted in their internal reflection by an object with a higher refractive index.
In a typical optical system, total internal reflection occurs when a light ray inside a higher-index medium reflects completely at a boundary between the medium and a second, lower-index medium.
