The vivid and clear way of virtual scene presentation in Virtual Environments (VE) is nearly exclusively accomplished by stereoscopic displays. Depth perception with these displays differs from the viewing conditions in reality and causes usability problems. For this reason three important aspects of visualization at a stereoscopic workbench display were(More)
Planar passivated germanium photodiodes have been developed whose useful response at 22 degrees C extends from 0.6 microm to 1.85 microm at a nominal operating voltage of 20 V. Typical characteristics at 22 degrees C are diode capacitance, 100 pF/cm(2); rise and fall times, 10 nsec; leakage current, 2.5 mA/cm(2) ; D*(1.54 microm) approximately 2.5 x 10(10)(More)
This work is focused on realization of DWDM system of 1. 6 Tb/s ultra high capacity using duobinary return to zero modulation scheme with EDFA and dispersion compensation scheme. Duo binary format is used as it is suitable for high spectral efficiency at large transmission distance. 40 channels having capacity of 40 Gbps data rate each are multiplexed with(More)
Exploration of a Virtual Environment (VE) might vary as well in applied technology as in the conceptual design. A conceptual difference of exploring style and navigation type relates to the degree of freedom a user possesses. It ranges from completely unrestricted to completely restricted navigation. To assess the impact of different exploration styles, an(More)
Current policies of the Alliance require the constant development and acquisition of new technologies and equipment to support the individual soldier. Applying different types of modeling and simulation (M&S) for the design of equipment has been advantageous in the past. This has gained importance ever since the dismounted soldier is considered as a system,(More)
The concepts of Virtual Reality (VR) and Virtual Environments (VE) have been introduced as powerful methods for presenting complex three-dimensional scenes. The widely used VR-displays like Workbenches (large-scale horizontal projection plane) and CAVEs™ (secluded room of projection planes) differ mainly from conventional monitors by allowing a stereoscopic(More)
