Optical variosystems that form the required diameter of the Gaussian beam waist and perform its smooth longitudinal movement with a constant diameter for laser technologies, processing materials, moving microobjects, etc., are considered. A combined method based on a movable tunable-focus lens for changing the optical characteristics of laser variosystems is proposed. The features and fundamental differences between the laws of transformation of Gaussian beams by optical systems of different structures for the dimensional synthesis of laser variosystems are discussed. Based on these laws and the theory of laser optics, a method for the dimensional synthesis of one- and two-component laser variosystems is developed, an algorithm for their automated synthesis, and an example of calculation are given.
The paper presents a lightguide system with stair micromirror structure for see-though glasses. We use stair micromirror structure to out-couple virtual image out of the lightguide. It allows extending eye motion box, where whole virtual image can be seen by a user. The design principle is described, as well as main achieved parameters.
Key theoretical concepts advanced by the Bauman MSTU scientific school 'Zoom lens design' are discussed. These include methods for design of both classical and laser zoom lenses, systems with linear and nonlinear relations between the displacements of components, basics of professor I. I. Pakhomov's theory of generalized parameters, a method of paraxial synthesis of multicomponent zoom systems, a method of aberration synthesis of zoom systems in the approximation of the third- and fifth-order aberrations. The effectiveness of the described methods is illustrated by examples of designing zoom systems with superior optical characteristics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
