 Coherent backscattering

Coherent backscattering is an optical phenomenon that occurs when coherent light, such as that from a laser, interacts with a disordered medium, such as an opaque or rough surface. This effect is characterized by an increase in the intensity of light that is scattered back in the direction of the incoming beam due to multiple scattering events within the medium. Here are the key points regarding coherent backscattering: 1. **Interference**: The phenomenon arises from the interference of scattered waves.
