Multifunctional optical element and method using multiple light scattering

An optical element using multiple light scattering, comprising:

• a wavefront controller configured to control a wavefront of a signal beam split from coherent light;
• photorefractive materials on which the signal beam having the controlled wavefront and a reference beam split from the coherent light are incident to form an interference pattern and on which the formed interference pattern is recorded;
• complex media on which the signal beam having the controlled wavefront reconstructed as the reference beam illuminates the photorefractive materials on which the interference pattern has been recorded again is incident;
• and
• a measuring unit configured to control and measure properties of light passing through the complex media based on multiple light scattering generated by the complex media.

A scattering optical element, comprising:

• photorefractive materials on which an interference pattern formed based on light having a wavefront controlled through wavefront optimization is recorded;
• and
• complex media on which light radiated to the photorefractive materials and the light having the controlled wavefront generated based on the interference pattern are incident and configured to transmit or reflect the incident light,
• wherein the light incident on the complex media generates multiple light scattering controlled by the complex media, and a wavefront of the multiple-scattered light is controlled so that the wavefront indicates a predefined desired optical field.
