Extending the Imaging Depth of Field through Scattering Media by Wavefront Shaping of Non-Diffraction Beams

Increasing the depth of field (DOF) is a crucial issue for imaging through scattering media. In this paper, an improved genetic algorithm used to modulate wavefront light media, by which high-quality refocusing and media are achieved. Then, DOF system effectively extended further modulating refocused beam into non-diffraction beam. Two kinds beams, i.e., Bessel Airy beam, were produced as demonstration. The experimental results show that compared Gaussian combining shaping or can be factor 1.1 1.5, respectively. proposed method helpful technical development with large DOF.
