Abstract: Disclosed herein are a multifunctional optical element and method using multiple light scattering. An optical control method using multiple light scattering may include the steps of splitting coherent light into a signal beam and a reference beam, controlling the wavefront of the signal beam, forming an interference pattern by making the signal beam having the controlled wavefront and the reference beam incident on photorefractive materials, recording the interference pattern on the photorefractive materials, reconstructing the signal beam having the controlled wavefront by the interference pattern by radiating the reference beam to the photorefractive materials on which the interference pattern has been recorded again, and controlling the properties of light passing through complex media based on multiple light scattering generated by the complex media as the reconstructed signal beam is incident on the complex media.
