DEVELOPED COMPUTER PROGRAMS FOR OPTICAL DESIGN

• Program for the calculating aberrations in FORTRAN for the Digital Equipment Corporation's PDP 11/34 in 1984.
• Program for the calculating aberrations and their graphical representation in FORTRAN for the Control Data Corporation's CYBER 170 model 720. For the graphical representation is used PLOT-10 (standard graphical library). Program is developed in 1985.
• Program for:
  • optical calculations;
  • accepting measured data via HP-IB bus;
  • comparing with the calculated data from the optical design;
  • various graphical representations.
• Program is written in HP BASIC ver. 4.0 for the Hewlett Packard HP 9000 Technical workstation series 200 model 236 (HP 9836) in the period from 1986 to 1987.
• Program called ADOS (Automatic Design of Optical Systems) for the complete design of the optical systems from the specification of the starting data through ray trace, calculation of the Seidel third order aberrations, real aberrations, spot diagrams and MTF, classical optimization using dumped least squares, graphical representation of the optical system, its aberrations, spot diagrams and MTF and preparation of the script file for the AutoCAD for further (mechanical) design of the optical systems. Program is written for the IBM PC AT compatibles and developed in the period from 1988 to 1990.
• Program called ATOS (Automatic Tolerancing of Optical Systems) for:
  • calculating tolerances of the optical system elements according to desired image quality;
  • directly accepting measured data and comparing it with the design data;
  • comparing influence of the any desired tolerance, class of the tolerances, or all tolerances on performance of optical system.
• Program is written in ANSI C. User interface is programmed in X Windows ver. 11 release 2 with the HP X Widgets. Graphical library is Starbase (standard graphical HP library). Program is developed on Hewlett Packard HP 9000 Technical workstation series 300 model 330 (2D Graphics Workstation) with HP-UX rev. 6.5 in the period from 1991 to 1993.
• Program for the global optimization of the optical systems using Genetic Algorithms and Evolutionary Strategies as a part of the program ADOS from 1994 to 1997. Program and research is a part of Ph.D. Thesis.

M.Sc. THESIS

M.Sc. Thesis with title "Contribution to the optimization of the design of optical systems with personal computers" is done on the Faculty of the Mechanical Engineering, University of Belgrade. In this thesis classical methods in the optimization of the complex systems are shown. After detail mathematical investigation dumped least squares method is chosen. This method is adapted for the optimization of optical systems and whole program for designing and optimization of optical systems are developed. Several types of objectives are optimized and results are discussed.

Ph.D. THESIS

Ph.D. Thesis with title "Possibility of applying genetic algorithms in the optimization of the double Gauss objectives for passive night sights" is done on the Faculty of the Mechanical Engineering, University of Belgrade. In this Ph.D. Thesis modern methods in the optimization of the complex systems are shown. Following methods for optimization are chosen: adaptive steady state genetic algorithm, two membered evolution strategy, multimembered evolution strategy which are adapted for, and with success applied in the optimization of the optical systems. Great number of the optimizations of various types of the objectives, which are used in military systems, is done. Results of the optimization are compared with corresponding results of the optimization by the dumped least squares method. Those optimization methods are very powerful means, which allows lens designer more freedom in designing good optical systems and in researching new ones.
