“…Two reconstructions are used to form a red-green anaglyph which is displayed to the user wearing colour coded lenses. More detailed procedure how to form an anaglyph from a digital hologram is described in [8]. In order to compensate for possible background IR interference, the results of the reference IR measurement are subtracted from the results of the actual IR measurement.…”

In the paper we introduce the novel intuitive user interface (UI) which is based on Wireless Sensor and Actuator Network (WSAN) technology and is implemented as a glove with a set of sensors for capturing user's gestures. The proposed UI is applied for interacting with a conventional 3D display and controlling the reconstruction of digital holograms. To the best of our knowledge the suggested interface is the first one, which is intended specifically for controlling the reconstruction parameters of digital holographic data. The suggested system includes the inter-cognitive communication as an important design parameter. In the paper we discuss in details the implementation of the interface and present the results of the experiments, in which the suggested UI was used to control the reconstruction of the holograms depicting industrially manufactured 3D objects. Based on the presented results, we distinguish the features of the developed UI and discuss the possible industrial applications of digital holography and of the suggested interface.

“…1). Use of this special property has been reported with conventional displays for reconstructing one perspective at a time (i.e., single-perspective case) in [8]. The real-life problem is that a single-perspective cannot typically accommodate all the data available in a hologram.…”

Stereoscopic display technology uses two-dimensional device to show three-dimensional (3D) scene with great significance. After fully studied 3D stereoscopic display technology which is widely used currently, the generation approach of stereo pairs is presented. 3D Delaunay triangulation method is adopted to perform triangulation operation on volumetric image model before applying dynamic display method is applied to achieve better display effect. Furthermore, 3D display of the volumetric model is realized by using Direct3D rendering technique to make the observer watch better 3D effect by wearing glasses. Research results have good future in displaying new products for web application.

This paper proposes a method to generate a stereoscopic image pair from a digital hologram by considering the situation that digital hologram data is serviced but the end-user does not have the proper display equipment, etc. We use Fresnel transform as the method to convert a digital hologram into an image. Each image of the stereoscopic image pair uses a part of the given digital hologram and the sizes of the two partial digital holograms for the two images are chosen to be the same. Here, the size of the image is adjusted by the size of the partial digital hologram and the disparity between the pair images is adjusted by the distance between the centers of the two partial hologram. This paper also deals with how to adjust the size and the disparity of the images. In this paper the generated stereoscopic images are implemented as an anaglyphic display type to confirm the feeling of distance by wearing the red-blue glasses.
