The need for focused, hard X-ray investigations of the Sun
Understanding accelerated particles at the Sun is one of the most important problems in heliophysics. Flare-accelerated particles have huge energies; are an important source of particles in the heliosphere; and are the most important corollary to other areas of high-energy astrophysics. This paper describes the scientific motivation for X-ray studies of particle acceleration at the Sun
Hardware accelerator for real-time holographic projector
With increasing popularity holographic method, 3D scene and augmented reality, needless to say, that 3D holography would be playing the most important role of real-time recording display. This paper demonstrates a setup that shows and records the scene in a real-time 3D appearance. We speed up the holographic processing by using a hardware accelerator to take advantage of its parallel specificities (architecture). The results clarify the system’s ability for viewing the holographic objects by applying four cameras running at the same time with a difference in partial of millisecond attributed to reason the clock of cameras and the VGA update.</p
Design and characterization of light field and holographic near-eye displays
The light field and holographic displays constitute two important categories of advanced three-dimensional displays that are aimed at delivering all physiological depth cues of the human visual system, such as stereo cues, motion parallax, and focus cues, with sufficient accuracy. As human observers are the end-users of such displays, the delivered spatial information (e.g., perceptual spatial resolution) and view-related image quality factors (e.g., focus cues) are significantly dependent on the characteristics of the human visual system. Retinal image formation models enable rigorous characterization and subsequently efficient design of light field and holographic displays. In this chapter the ray-based near-eye light field and wave-based near-eye holographic displays are reviewed, and the corresponding retinal image formation models are discussed. In particular, most of the discussion is devoted to characterization of the perceptual spatial resolution and focus cues.acceptedVersionPeer reviewe
