An experimental study of the color reproduction quality of RGB color components, white and some “composite” colors in the developed augmented reality device based on two waveguides with diffraction elements was carried out. The color gamut of the device is determined. Color characteristics were analyzed by color coordinates in the xy system, presented on the chromatic diagram, and are given in the work.
An alternative holographic wavefront analiser scheme based on the light guide plate with computer-generated holograms and diffractive optical element is proposed. Advantages of the scheme are the absence of a maximum of zero order of diffraction in the photodetector plane and potentially better recognition of aberrations.
The work is devoted to the calculation of the optimal parameters of diffraction gratings for input and output of radiation from the holographic lightguides for augmented reality glasses. Two main stages can be distinguished, namely: the calculation of the grating’s period in each of the optical lightguides to obtain a multicolor image in a large field of view, and the calculation of the height of the relief profile (to maximize the diffraction efficiency).
This paper analyses the possibility of obtaining a full color image using the holographic indicator based on a light guide plate with diffractive optical elements (DOEs). The parameters of the optical collimator system are calculated as well as the experimental results on generation of full color images are presented.
In this article analysis the possibility of using ion-plasma technology for etching the diffractive optical elements (DOE) directly in the glass, not in a layer of photosensitive material is described. Experimental samples on the light guide substrates for displays and signs-symbolic information indicators are obtained, as well as their basic parameters, such as the depth and shape of the surface topography and the diffraction efficiency are investigated. The experimental results showed the fundamental possibility of manufacturing the DOEs directly on the glass for the display of information systems.
