Extraction and restoration method of underwater turbulence phase distortion information based on holographic interference

This paper integrates the background of holographic interference and, based on Real-time coherence holography, proposes a method for extracting and restoring phase distortion in underwater turbulence images. By contrasting holographic interference under weak to strong oceanic turbulence (using a plane light wave through a static water region as a reference light source). Extracting complex amplitude information from multiple holograms, the phase information is transmitted to the spatial light modulator (SLM) to output phase-conjugate light waves, effectively compensating for wavefront distortions caused by the scattering medium, achieving the reconstruction of the target beam. This approach circumvents the utilization of costly wavefront sensors and effectively rectifies phase distortion in turbulent environments, thereby yielding more precise and lucid imagery. Consequently, it exhibits significant potential for practical applications.
