Background:

  • Generating uniform 2D spot arrays using optical masks is crucial for various applications.
  • Previous methods focused on uniform peak intensity, limiting energy distribution control.

Purpose of the Study:

  • To derive an optimal analytical solution for phase-only optical masks.
  • To achieve uniform energy distribution across all spots in a 2D array.

Main Methods:

  • Developed an optimal analytical solution for phase-only optical mask design.
  • Applied mathematical optimization techniques.
  • Set constraints for equal energetic content in each generated spot.

Main Results:

  • Successfully derived an analytical solution for phase-only optical masks.
