(1) and by Athale et al. (2). The main advantages of e-beam techniques are the capabilities of focusing electron beams of very narrow dimensions (typically 0.1 to 10 microns) and positioning these beams very accurately on the writing surface. Ultra flat glass plates, plated with chromium then coated with a thin layer of electron sensitive photo-resist, form the writing surfaces. Exposure of the material to the computer located e-beam is followed by development of the photo-resist, and then by etching of the exposed chromium to produce a binary pattern on the glass substrate. Suitable patterns written in this way on the chromium provide a convenient means of achieving holographic elements.","PeriodicalId":394593,"journal":{"name":"Topical Meeting on Holography","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123508697","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}

Diffraction of electromagnetic waves by spatially periodic media has been analyzed by numerous authors over the last fifty years [1]. In almost all previous analyses, only diffractive structure with one single grating (and its harmonics) were considered. Recent applications for holographic optical elements include associative storage, optical computing, multiple holographic storage, beam coding, multiple beam generation and combining, multi-color displays, multi-color filtering, beam shaping, synthetic lenses, interlaced elements, and multifrequency beam mixing. In these applications, two or more gratings of arbitrary spatial frequency and slant exist simultaneously within the diffractive element. Case [2] developed a couple-wave analysis for Bragg-angle diffraction of light by two superimposed thick phase holographic gratings. Alferness and Case [3], utilizing a thin grating decomposition method, examined both the direct and the cross coupling among the incident beam and the two first diffracted orders in such a structure.","PeriodicalId":394593,"journal":{"name":"Topical Meeting on Holography","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116505266","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}
