CONFERENCE PROCEEDINGS FREE ACCESSA new method is proposed to draw up a hologram using a Moire pattern of interference fringes on the base of the local approximation. Numerical calculation is carried out about reconstruction of the wavefront and formation of 3D images to show validity of a hologram made up from a Moire pattern.View full abstractDownload PDF (882K) -

CONFERENCE PROCEEDINGS FREE ACCESSRecording of a 3D image using a Moire pattern of interference fringes is proposed for a purpose of dramatic compression of data for 3D images. Information of 3D images is recorded as a Moire pattern of interference fringes, and a hologram is made up from this pattern. Numerical results about formation of a 3D image are presented.View full abstractDownload PDF (1027K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn order to reduce raster moire fringes appearing on color CRTs, electron beam profiles were investigated. By analyzing the beam profile in the spectral frequency domain, the contrast of the combined moire patterns of modes(1, 1)and(2, 2)was found to become proportional to the spectral intensity, 2/S, of the beam profile, where S is the scan line pitch. As a result of examining relationships between C-G1 electrode separation of an A-EA-MDF electron gun and spectral intensity, it became clear that the spectral intensity at 2/S decreases with larger electrode separation. Moire fringes can be reduced without deteriorating the resolution when C-G1 separation is 90 μm.View full abstractDownload PDF (573K) -

CONFERENCE PROCEEDINGS FREE ACCESSFor expressing gray levels, color PDPs employ a technique of pulse-number modulation within a TV field time by dividing the field into sub-fields. The image of the pixel formed on retina spreads, when the observer's eye traces the moving picture on a PDP. This phenomenon is applied to the virtual pixel technique, which assumes virtual pixels on retina for increasing the apparent resolution of PDPs. In this paper, the principle and practice of the virtual pixel technique for doubling the PDP resolution is explained. Also the width of virtual pixel and the number of expressing gray levels for doubling the PDP resolution are examined for the stripe and delta pixel arrangements.View full abstractDownload PDF (937K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe quantum efficiency of the New Super-HARP target has been improved to obtain an even better picture. To increase the quantum efficiency for green incident-light, two improvements have been made to the target. The first is doping the target with a suitable amount of tellurium on its incident-light side. The second is reducing the lithium-fluoride-doped layer to about 60% of the thickness of the conventional target. The improved version of the New Super-HARP target has higher quantum efficiency. Its quantum efficiency for green incident-light was evaluated to be double that of the conventional target. It was confirmed that the S/N is improved by three dB. that is, shot noise is reduced by three dB.View full abstractDownload PDF (672K) -

CONFERENCE PROCEEDINGS FREE ACCESSWith the aim of creating a highly sensitive solid-state image sensor we developed a new CMOS image sensor that was made by overlaying a HARP(high-gain avalanche rushing amorphous photoconductor)photo-conversion film on to the CMOS readout circuit. Prototype sensors were fabricated that used a new MOS transistor to increase breakdown-voltage in the readout circuit. We developed connecting processes that were use to connect the HARP film to the readout circuit. Stable operation of the sensor was observed when the target voltage of 60 V was applied.View full abstractDownload PDF (855K) -
