The particular application described here is a residue arithmetic optical matrix-vector multiplier with position coded information1, using a Hughes liquid crystal light valve2. Superimposed multiple exposure phase holograms in a silver halide emulsion are used to store multiple mappings1 in the form of an addition truth table. The angular sensitivity of the emulsion allows constructing and reconstructing a different image in the hologram, corresponding to associated reference and reconstruction beam directions. The reference beam is produced using a single mode optical fiber which is repositioned for each exposure to generate reference beams with different directions.","PeriodicalId":394593,"journal":{"name":"Topical Meeting on Holography","volume":"3 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":"115025326","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}

Transmission of signals within a single chip and between chips presents limitations in power dissipation and timing. Replacing critical electronic signal transmission lines with optical signal paths can result in the following advantages: 1) Fewer layers of metalization and polysilicon on the chip; 2) Elimination of clock skew due to limited electronic signal transmission speed; 3) Faster point to point communication; 4) Reduction of the necessary electrical pinouts per chip; 5) Direct access to locations away from the perimeter of the chip; 6) Access to critical signal injection points for testing; 7) Custom configuration during assembly to bypass failed elements; and 8) A path toward dynamic reconfiguration of processing element connections.","PeriodicalId":394593,"journal":{"name":"Topical Meeting on Holography","volume":"194 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":"126051230","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}

The change in refractive index of the fluid caused by temperature and density changes is the basis of these methods. These non-intrusive probes have several advantages over mechanical probes such as, very high spatial and temporal resolution, absence of probe induced perturbations, etc. Mach-Zehnder interferometers are frequently employed for analysing heat transfer in fluids. But the need to maintain nearly identical path length in the two limbs (hence requires two identical cells with optically flat windows, one cell being used for compensation) has limited its application considerably. Holographic interferometry, on the other hand is especially well suited to studies with transparent fluids since there is no need for special windows or cells.","PeriodicalId":394593,"journal":{"name":"Topical Meeting on Holography","volume":"59 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":"123371438","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}
