Detector consists of the two elements - glass plate and silicon chip. There are two flow channels formed at the glass-silicon interface - one for detection and the other for reference. Two highly symmetrical groups of resistors were aligned with the channels and, in the last stage of the fabrication sequence, released from the silicon substrate. Some of these resistors act as the heaters, the other ones as the detectors (thermoresistors) to detect changes of the flowing gas temperature. Tubing - gas inlets and outlets - was positioned at the detector edge, in the Si-glass interface plane. BSC-type electrical contacts application enabled very convenient bonding pads location. The Contacts formation process was optimized and integrated with the other technological steps.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122699766","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}

Brzózka","doi":"10.1117/12.517117","DOIUrl":"https://doi.org/10.1117/12.517117","url":null,"abstract":"The total concentration of heavy metal ions was measured with the use of a highly sensitive reagent (4-(2-pyridylzo)-resorcinol (PAR)). Because of PAR chelates are slightly soluble in water and their forming is not selective, the analytical procedure for Cd, Cu, Hg, Pb, Zn determination was developed to perform the analysis in an aqueous environment without the need of inconvenient and time-consuming extraction. A proposed analysis method is more useful in comparison with classical FIA analysis what is crucial during fast classification of various natural water samples. To minimize the chemicals consumption such a classification can be performed in a specially designed microsystem. The Y- shape microchannel structure with a mixing area was made by fine engraving in PMMA plate and sealed with the PDMS one. The M2+-PAR complex forming conditions were determined for each of the chosen metal ions. The solubility of formed complexes was better when a micellar environment was created by the addition of a non-ionic surfactant (Triton X100). Next the synthetic mixtures of Cd, Cu, Hg, Pb, Zn ions were prepared to obtain total molar metal ions concentration in the range from 10-6 to 10-4 M and measured after on-chip reaction. A tap water and HAC-sample (Highest Allowable Concentration, ΣMe=1,2•10-5 M) were also measured. The detection was performed in a special flow cuvette and spectra measurements were carried out using diode array spectrophotometer and CCD detector.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"381 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122927727","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}

A central interference fringe of polychromatic light is used to determine a reference distance. The method is based on comparison of two elements i.e. gauge blocks with one of them serving as a reference. The displacement of an interferometer reflector between the reference points related to the reference block and a measured gauge block is determined. The measurement of displacement and the detection of the gauge block positions were carried out within one optical axis. The presented measuring system is especially predestined as an extension to commercially available interferometers, making possible their application for a calibration procedure of gauge blocks.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129248289","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 sensor head is the ending of the large core polymer optical fiber. The head works on the reflection intensity basis. The reflected signal level depends on Fresnel reflection and reflection on suspended matter when the head is submersed in solution. The sensor head is mounted on a lift. For detection purposes the signal includes head submerging, submersion, emerging and emergence is measured. This way the viscosity turbidity and refraction coefficient has an effect on measured signal. The signal forthcoming from head is processed electrically in opto-electronic interface. Then it is feed to neural network. The novelty of presented sensor is implementation of neural network that works in generalization mode. The sensor resolution depends on opto-electronic signal conversion precision and neural network learning accuracy. Therefore, the number and quality of points used for learning process is very important. The example sensor application for examination of liquid soap concentration in water is presented in the paper.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123648506","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}
