Abstract
Peculiarities of constructing the main control systems in a laser pattern generator designed for synthesizing the microrelief of diffractive optical elements on 3D surfaces are considered. Particular emphasis is given to problems of designing an autofocusing system. For these applications the system was done as a self-tuning system with functions of automatic search, capture, and retention of the record surface at a distance of the best focusing. Results of writing diffractive optical elements on different types of surfaces, including flat surfaces, coated with chromium or photoresist films, and a spherical surface coated with a chromium film are presented.
