Since the memory capacity is governed by the ratio of the inhomogeneous-to-homogeneous linewidths, 103~106 images can be recorded in a single sample spot. An extensive study on holebuming holography has been carried out by Wild et.al for organic dye-doped polymer samples1-4. On the other hand, holeburning holography has not been carried out for crystal samples, because there are few crystals exhibiting persistent holes. We have performed holeburning holography to record images for Eu3+:Y2SiO5 crystal which has been known for exhibiting persistent holes. Moreover, Eu3+:Y2SiO5 has other unique features5,6 such as narrow holewidth and high holeburning quantum efficiency. By using this crystal, we have also succeeded in real-time recording of a moving object.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115798146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These photofunctional surfaces are called \"command surfaces.\" (Fig.1)1 The Langmuir-Blodgett (LB) technique provides importance information on the design of the surface layer. The LB film preparation condition should influence, to a large extent, the aligning behavior of the nematic LC as formerly proposed by Hiltrop and Stegemeyer.2 The present work is undertaken to elucidate the relationship between the conditions of the LB film conditions and the LC aligning behaviors. For Az LB film preparation, two sets of amphiphilic Az side chain polymers are employed, the backbone being (i) poly(vinyl alcohol) and (ii) poly(ethyleneimine). Polymeric materials are required to obtain highly photoreactive Az LB films. Single monolayers are prepared as the Az LB films throughout the investigation to avoid complexity of the film structure.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115445263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike other optical memories, CTDOM is capable of providing ultrahigh image transfer rates and offers features such as in-memory image processing.5 However, difficulties arise in using the conventional time-domain approach to image storage, namely multiple images per frequency channel. For example, existing image composers such as an electronically-addressed spatial light modulators (SLM) do not have switching times fast enough to accommodate the required recording speeds (≳ MHz). High-power pulsed lasers are needed to make retrieved images detectable by electronic cameras. In addition, features such as random frame (or page) access and variable playback speed are not available with the conventional approach.","PeriodicalId":443330,"journal":{"name":"Spectral Hole-Burning and Related Spectroscopies: Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126111262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in a class of porphin derivatives - free-base and metallotetrabenzoporhines (TBP) - the former effects are substantially reduced. As a result, quasiline structure of S0-S2 transitions of ZnTBP in an Ar matrix [2], and later of ZnTBP in supersonic expansions [3] were observed.
