Novel optical elements containing semitransparent wavelike films embedded into the bulk of transparent material, which form a reflection image without transmitted light distortion, are studied. The dynamic theory of light diffraction by a locally periodic multilayer semitransparent wavelike film is developed. A simple analytical formula for near Bragg diffraction order intensity is obtained for the case when only one diffraction order lies within the hologram angular selectivity. The phase modulation of light transmitted through the optical element containing wavelike films is estimated for single-layer and multilayer wavelike films with an arbitrary shape of surface. The restrictions on the structure parameters for which transmitted light distortions would be negligible are obtained. A new type of high quality color hologram is proposed and shown to be feasible by calculation of hologram diffraction efficiency and spectral selectivity for three colors. Other possible applications, such as monochrome and color head-up and head-mounted displays, and imaging on spectacle lenses, are discussed.

“…A special example of an OE containing a semitransparent thin film that does not distort transmitted light is an interference structure recorded in a bulk medium using ultrashort laser pulses propagating towards each other. Such structures demonstrate a geometrical-optical mechanism of wavefront reconstruction, which is different from the holographic one [6,7].…”

The recently proposed optical elements containing semitransparent wavelike films embedded into the transparent material are investigated. Such optical elements do not distort a wave transmitted through them. Novel optical elements can be fabricated using well-known embossing methods. Their possible applications are discussed. The optical elements containing holographic wavelike films can be used for color holography, for augmented reality wearable glasses, as a beam combiner for head-up displays. The optical elements containing diffuse wavelike films can be used as an alternative for tinted car windows, instead of mirror-glass windows in high-rise buildings, for shop-windows, for one-way privacy windows, for printing images on eyeglasses. The scheme of a waveguide display with a single-layer holographic wavelike films is analyzed. The feasibility of the proposed applications is verified by estimation of the optical elements’ parameters and computer simulation, and measurements conducted on an experimental specimen.

“…переходе от отражательного ОЭ к его пропускающему эквиваленту координата каждой точки поверхности ОЭ вдоль его оптической оси должна быть умножена на 2/(n − 1) (где n -показатель преломления материала, из которого изготовлен пропускающий ОЭ). Технологии получения ОЭ с поверхностью необходимой формы зависят от этой формы, размеров ОЭ и необходимой точности [3]. В случае, если возможности технологии не позволяют получить требуемый диапазон изменения высоты поверхности ОЭ, может быть использован какойто из вариантов, описанных ниже.…”

“…В отличие от голографического восстановления при ГО восстановлении нет дифракции восстанавливающего излучения периодической интерференционной структурой. Это делает процесс восстановления ахроматическим, т. е. позволяет восстанавливать неискаженный волновой фронт светом с длиной волны, отличной от длины волны в процессе записи [2,3]. ГО механизм восстановления волнового фронта был предложен для голографии.…”

The mechanism of wavefront reconstruction by a geometric-optical reflection of reconstructing light from surfaces with constant phase differences between the object and reference waves used to record the interference fringe structure in the medium bulk is analyzed. This mechanism is compared with the holographic one. Experiments in volume medium and in planar optical waveguide were carried out. Several types of achromatic optical elements are proposed. The optoacoustic focusing element, which can create a great local stress in a special shaped area inside the matter, is discussed. The possibility of the ultrashort pulse temporal reconstruction is demonstrated.
