dc.description.abstractΣχεδιασμός ολογραμμάτων με την βοήθεια υπολογιστή παραμετροποιώντας μια συνάρτηση κόστους ώστε να λαμβάνεται υπόψιν οι κατασκευαστικοί παράγοντες και περιορισμοί κατα τον σχεδιασμό τους. Κατασκευή κώδικα προσομοίωσης σε διάταξη 2f για εξέταση των ολογραμμάτων. Κατασκευή των ολογραμμάτων σε ατσάλινη επιφάνεια με χρήση fiber λέιζερ και εξέταση των αποτελεσμάτων.el
dc.description.translatedabstractThe purpose of this thesis is the design and fabrication of computer-generated holograms taking into consideration various factors. Beginning with an introduction to holography, its mathematical description and current applications we procced to the fundamentals of designing holograms using computers. Cost functions and optimization algorithms are introduced followed by procedures of fabricating CGH such as fiber laser micromachining. On the second part of the thesis, theory from the first part in implemented and a program simulating diffraction and propagation is coded. Furthermore, a program designing CHM is written that has the options to design based on square or cyclical pixel shape. A custom cost function is integrated on the program that forces changes based on the density of pixel to be engraved by the laser. In the end, the CGH that where designed by the program and fabricated using a fiber laser were evaluated using optical reconstruction. Both programs’ results are compared to a commercially available optical design software to check the validity of the programs’ results.el
