Abstract:

Subject of study. The fullcolor holographic/diffraction optical elements inherently representing the multifocal achromatic imaging lenses were investigated. The tasks of modeling and recording of these elements were also discussed. Aim of study. The research and development of compact optical systems for Augmented Reality/Mixed Reality/Extended Reality devices with wide field of view and eyebox is the main target. Method. The analog recording scheme with several sources in signal branch was used. The specialized software MatLab and Optic Studio was used for modeling and evaluation of parameters of the optical systems of the Augmented Reality/Mixed Reality/Extended Reality devices. Main results. The authors have proposed several modifications of such elements; the possibilities and limitations of each variant, and also the parameters of the prepared samples were evaluated by means of simulation, on the bases of which the best sample was chosen. The total efficiency of 30–40% for such elements was achieved for each wavelength in RedGreenBlue color model (460, 514/532, 640 nm). Practical significance. The technology for registration of holograms with several sources in signal branch allows to significantly enlarge the size of the eyebox without sacrificing the width of the angular field of view, to downsize the device of virtual and augmented reality.
