The results of optimisation analysis of the system construction and testing procedure are here discussed.

INTRODUCTIONFerroelectric materials have wide spectrum of application in contemporary electronics. That is why the newmaterials obtaining previously defined properties are desired. Ferroelectric single crystals showing electric response on the temperature extortion are called pyroelectrics. The most popular application pyroelectrics foundin detection of the JR radiation. Because of its unique properties such as direct conversion of JR radiation to theelectric current, wide spectrum of operation, high sensitivity, low capacity, low production cost, large detectionareas, no need of additional cooling, pyroelectric single crystals are the only solution in many cases.TGS belongs to the ferroelectrics with hydrogen bond and is well known material for the pyroelectric detectors.Unfortunately its electric properties are changing with time and may vary even in case of samples cut from the","PeriodicalId":156625,"journal":{"name":"Systems of Optical Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129786955","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}

Considered questions concern problems with reliable processing of noninvasively acquired biooptical signals that are influenced by noises, artifacts and other disturbances. The proposed procedures of signal conditioning make possible effective acquisition of useful parameters of a raw noisy PPG signal. Novel design of the adherence circuit that allows eliminating the disturbing low-frequency trend has been presented. Results of verifying studies, where real signals acquired with transmission sensor were processed using this and circuit and classical linear circuit, are discussed.","PeriodicalId":156625,"journal":{"name":"Systems of Optical Security","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123681515","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}

We present a method of fabricating 8-level DOEs with submicrometer feature sizes in a 3-step lithographic process. In each step a variable-shaped c-beam exposure system is used for writing the pattern that is transferred into substrate by reactive ion etching to form the phase profile. Using this technology several DOEs, including rectangular-apertured micro-Fresnel lens arrays and diffraction gratings were realized on quartz and GaAs wafers. The diffraction efficiencies of these elements were measured to be up to 92%. The lens arrays showed uniform focusing characteristics, and each lens exhibited a good quality of the focused wave front.","PeriodicalId":156625,"journal":{"name":"Systems of Optical Security","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130959577","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}
