Abstract

The object of this paper is to present the experimental validation of aberration compensation into a novel design for seethrough head-mounted displays. The proximity of the user's head generates high geometrical constraints. To compensate for the resulting aberrations, we use both dynamic sequential image creation and dynamic adapted aberration compensation. The see-through head-mounted display is composed of a holographic mirror serving as a combiner and a phase modulation spatial light modulator which insures the dynamic phase correction. The first step of the work has consisted in the realization of the holographic combiner and the characterization of the phase modulation by the light modulator. An experimental analysis of the aberrations of the image beam has been conducted. Next, the implementation of the theoretical corrective phase function into the spatial light modulator has been realized. Finally, the experimental demonstration of the expected aberration compensation has been achieved.
