Paper Abstract

The ability to control the propagation of light through scattering media has great research significance in biomedical treatment and laser material processing. How to achieve effective focusing by modulating the laser beam passing through the highly scattering media is extremely important. In this paper, based on the traditional continuous sequence algorithm, improved scanning methods are used to modulate the phase of incident light wave-front, thus achieving effective focusing of the laser beam through the scattering media and increasing the convergency speed of the algorithm to nearly 1.5 times. Similarly, using continuous sequences and their optimization algorithms can focus the light into the desired pattern and the performance of three different scanning methods of continuous sequence algorithm are discussed.
