  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.
