| Summary: | This report will discuss in detail the implementation of a feedback-based phase modulation
method to obtain the optimum incident wavefront is by exploiting iterative optimization
algorithms. In particular, the optimization technique focused on and demonstrated with will
be the genetic algorithm. The description of the construction of a feedback algorithm based
on a model genetic algorithm for phase optimization and the logic behind it will be detailed
in the report.
Subsequently, the simulation results for the successful construction of the algorithm as well
as the implementation on the actual experiment set up will be shared in the report. The
hardware components used in the implementation include a He-Ne laser of λ=632.8, a Spatial
Light Modulator (SLM) and a diffuser. Observations and conclusions drawn based on the
simulation and actual experiment shall be described in further detail. |
