We present the development and investigation of a holography-based head mounted display (HMD) that uses the proprietary Viewing-Window (VW) technology of SeeReal Technologies to generate a holographic scene. Considering various specification requirements, such as field of view (FOV) and resolution, the development of the HMD system was implemented by means of the optical design software Zemax. A prototypical HMD was set up in the laboratory and several tests were conducted e.g. resolution limit, field of view, and spatial resolution of the holographic reconstruction to investigate the performance. The HMD system reaches a resolution limit of 2.2 cycles/mm at a distance of 1500 mm between observer and image plane. The FOV is 4.1° in the horizontal and 2.3° in the vertical direction. By tuning the focus of a camera it was demonstrated that the holographic reconstruction is spatially resolved in three dimensions. Taking into account all technical specifications and restrictions, the image quality of the HMD was evaluated as good. Using holographic imaging technique has been demonstrated to be suitable to avoid the conflict between accommodation and convergence of the eye and is a promising way in future HMD technology.
