ジャーナル フリーThe present state of 3-D display technologies is viewed from the point of 3-D video. First, different two categories are tried, and the merit and the demerit of each practical display method are mentioned. Next, new methods which have been recently developed are introduced with the key points. In future, observation of 3-D image should be natural and observers should not be tired. From this point of view, it becomes important the comparison of eye control between the case of real object observation and 3-D display observation. The researches of these progress are mentioned.抄録全体を表示PDF形式でダウンロード (495K) -

ジャーナル フリーRecent advancements of three-dimensional still image display by holography are introduced. The features of holography for displaying the image and the technical subjects to be solved are described first. The topics include the deep-image holography, hologram printer, color holography, compact reconstruction of hologram, and the image formation using computer. The display of image information using holographic optical element is also presented.抄録全体を表示PDF形式でダウンロード (578K) -

ジャーナル フリーA personalized holographic stereogram printing system has been developed. The system consists of an image processing PC, a system control device and a desktop one-step holographic stereogram printer. It takes less than 90 seconds including file-loading time to obtain a horizontal-parallax-only hologram image 30 mm × 22.4 mm on photopolymer film. The system is capable of producing not only reflection type holograms but also edge-lit type holograms by making a small change to the printer head. As applications of the edge-lit hologram, we propose a 360 degrees viewable cylindrical hologram and a compact edge-lit hologram viewer. The system can be applied to many applications such as portraiture, computer graphics, identification, computer aided design, visualization, medical imaging and so on. We will also describe about the consumer applications that will enable us to easily put personalized contents into the hologram via the Internet.抄録全体を表示PDF形式でダウンロード (1187K) -

ジャーナル フリーThe development of a large stereoscopic full-color LED display using a parallax barrier is described. An optimization of a viewing area that depends on the width of black regions between LEDs has been discussed and then its widening has been examined by using LED panels with different width of black regions. A method to enlarge the viewing areas of the display for observers with different interpupillary distances is proposed. Furthermore, elimination of the pseudoscopic viewing area by introducing black columns into the display has been discussed and confirmed by experiments.抄録全体を表示PDF形式でダウンロード (1056K)

ジャーナル フリーWe have proposed a new kind of glasses-free three-dimensional imaging system that is capable of presenting a white cloud-like object as if it were an arbitrarily shaped color object by filtering and coloring light rays using a pinhole-array and a spatial-color-filter. Simple 3D images floating in the air at about 40 cm have been successfully generated as a result of the experiment with Fresnel lenses, though the generated images lacked clarity. On the other hand, comparatively clear 3D images have been generated by direct imaging without the Fresnel lenses.抄録全体を表示PDF形式でダウンロード (904K) -

ジャーナル フリーThe authors propose a new function for a two-dimensional lens array that is composed of many gradient-index lenses. The length of the lenses is an odd-integer multiple of the half period of the optical path. The array produces pseudoscopic three-dimensional (3D) images with reversed depth. Two lens arrays are positioned at a suitable distance so that orthoscopic 3D images with correct depth are formed in front of the lens arrays. The combined arrays can capture, transmit and display 3D images without other devices. This function is similar to that of integral photography.抄録全体を表示PDF形式でダウンロード (831K) -

ジャーナル フリーHologram screen for auto-stereoscopic 3-D display has the merit that the size of viewing zone can be controlled adequately. But it has fundamentally color dispersion and color aberration when the hologram screen is illuminated by white light. Therefore, it is required that little color dispersion and little color aberration is realized. In this paper, we propose the hologram screen attached with Fresnel lens, and the effect of the screen is demonstrated by simulation and by a experiment.抄録全体を表示PDF形式でダウンロード (725K)

ジャーナル フリーWe observed and discussed the effects of Free Electron Laser (FEL) irradiation to cholesterol accumulated in the regions of arteriosclerosis in the human carotid artery, by an Infrared micro spectroscopy (FT-IR). As a result of this study, we found that we could selectively remove cholesterol only without effects to normal parts of the human body, in irradiating 5.75 μm-FEL that come from a ester bond of cholesterol ester, under the condition that average power is 5 mW, power density is ∼16 W/cm2 and irradiation time is 30∼180 sec.抄録全体を表示PDF形式でダウンロード (3395K)
