CGDH Tools: Getting started in computer generated display holography

Popis výsledku v původním jazyce

First steps in computer generated display holography can be difficult for both students, researchers and engineers. One of the main reasons is that in order to make a computer generated hologram, one has to implement the whole chain that calculates optical fields, makes a hologram and allows to simulate its reconstruction. The aim of CGDH Tools is to provide the basic building blocks of such a chain and to show a few case studies that demonstrate step by step how to use them. CGDH Tools is a set of Octave/MATLAB/Scilab functions and scripts that try to be as simple and clear as possible; moreover, they are extensively documented. The functionality includes light propagation calculations (convolution based, angular spectrum based and single Fourier transform based with optional local frequency clipping), object wave calculations (point cloud, wavefront recording plane, stereogram, billboard based method, etc.), hologram observation simulation and various handy utilities. CGDH Tools can be used for teaching holography or wave optics, for simple diffractive optical element design or it can be used as a starting point when implementing advanced calculation methods. CGDH Tools can be freely downloaded at holo.zcu.cz.
