In this work, the phase structures of BaTiO 3 nanoparticles with sizes ranging from 2.5 nm to 10 nm were studied at various temperatures by using aberration-corrected transmission electron microscopy (TEM) equipped with an in-situ heating holder. The results implied that each BaTiO 3 nanoparticle was composed of different phases, and the ferroelectric ones were observed in the shells due to the complicated surface structure. The ferroelectric phases in BaTiO 3 nanoparticles remained at 600 C, suggesting a significant increase of T c . Based on the in-situ TEM results and the data reported by others, temperature-size phase diagrams for BaTiO 3 particles and ceramics were proposed, showing that the phase transition became diffused and the T c obviously increased with decreasing size. The present work sheds light on the design and fabrication of advanced devices for high temperature applications.

“…Scientists have been always trying to use an appropriate setup and a good CCD or CMOS camera, with a suitable pixel pitch, to make high resolution digital holograms [56,57]. Pixel count is an important factor in quality of holographic displays, and there have been always attempts to increase it [58]. In an experimental research which has used a high resolution CMOS sensor, full-color compact lensless holographic display has been evaluated [59].…”

Displayers tend to become three-dimensional. The most advantage of holographic 3D displays is the possibility to observe 3D images without using glasses. The quality of created images by this method has surprised everyone. In this paper, the experimental steps of making a transmission hologram have been mentioned. In what follows, current advances of this science-art will be discussed. The aim of this paper is to study the recent improvements in creating three-dimensional images and videos by means of holographic techniques. In the last section we discuss the potentials of holography to be applied in future.

A colour holographic display is considered the ultimate apparatus to provide the most natural 3D viewing experience. It encodes a 3D scene as holographic patterns that then are used to reproduce the optical wavefront. The main challenge at present is for the existing technologies to cope with the full information bandwidth required for the computation and display of holographic video. We have developed a dynamic coarse integral holography approach using opto-mechanical scanning, coarse integral optics and a low space-bandwidth-product high-bandwidth spatial light modulator to display dynamic holograms with a large space-bandwidth-product at video rates, combined with an efficient rendering algorithm to reduce the information content. This makes it possible to realise a full-parallax, colour holographic video display with a bandwidth of 10 billion pixels per second, and an adequate image size and viewing angle, as well as all relevant 3D cues. Our approach is scalable and the prototype can achieve even better performance with continuing advances in hardware components.
