This technique is well known for tens of years, its benefits are a potentially simple optical setup and low requirements to the data acquisition and analysis. Therefore it is a valuable method for online contactless velocimetry. The classical spatial filtering setup is based on a static grating in the optical detection path with at least one or two photodetectors. Newer developments are using line array or two-dimensional detectors (e.g. CCD or CMOS). Here the grating structure is realized by weighting the pixels in a signal pre-processing. The flexibility of adapting the grating to the application is much higher but the detector speed of the array sensors is much lower than that of the photodetectors in the classical setup. Both properties are important for a spatial filter sensor that can be used in a wide range of application. The novel micromirror array based optical spatial filter design that is presented in this paper combines the advantages of both state of the art systems. It utilizes fast photodetectors in combination with a very precise, flexible and high resolved differential grating that is realized by the micromirror array. The present paper gives a short overview on the spatial measurement technique, explains the micromirror array based sensor approach and shows the proof of concept.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117036875","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 main goal of the paper is to analyze the possibility to accurately estimate the status of a large scale distribution network, relying on a distributed measurement system, in a multi-area framework: to this aim, two-step state estimation procedures are considered. First of all, the network is divided into sub-areas, according to geographical and/or topological constraints. Then, in the first step, for each sub-area, a dedicated estimator is used, exploiting all the measurement devices available on the field. In the second step, data provided by sub-area estimators are processed, using different methods, in order to improve the knowledge on the operating conditions of the network, while keeping the communication “cost” low. Both first and second step can be performed in a decentralized way and with parallel processing, thus leading to reduced overall execution times. Test results, obtained on the 123-bus IEEE test network, are presented and discussed.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116385675","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}

In turn, optical interferometry is an adequate technique to measure nano/ micro displacements and to characterize these PFAs. An efficient method for optical phase detection is the n-commuted Pernick method (n-CPM), where only a limited number of frequencies in the magnitude spectrum of the photo detected signal are used, without the need to know the phase spectrum. The n-CPM has the advantages of being passive homodyne, direct, self-consistent, and is immune to fading. The dynamic range for optical phase measurements is from 0.2 rad to 100π rad. In this work, by using the n-CPM, a new PFA prototype designed by topology-optimization method is tested in terms of displacement linearity (relative to applied voltage) and frequency response.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123574938","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}

Recently, the attention has been paid to the use of complex excitation signals, meant as signals different from the sinusoidal ones and with wide frequency content. In particular, some studies have highlighted their suitability, respect to the sinusoidal one, in supporting the measurement, detection and quantification stages when “difficult cases” are explored (i.e. very short or annealed cracks). Generally, two class of signal have been proposed in literature. They concern with signals that have to be analysed in the time domain and signals analysed in transformed domains. The former class is represented by signal as the pulsed or pseudo-noise, while the latter contains signal as the chirp or multi-frequency as the best candidate. The author have placed their attention to this second class of signal and in this paper they propose an experimental comparison among different realization of these excitation signals suitably designed to improve the quality of experimental data when difficult cases are experienced.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129611581","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, this high sensitivity of the SPR biosensor systems has a side effect: a high sensitivity to noise present all over the system. The ambient temperature, the position of the components, the impurities in the light path, the photo detector instrumentation, are all noise sources that can degrade the information present in the signal. Preprocessing this signal before extracting the interest parameters and even the techniques used to extract these parameters can minimize the degradation effect of the noise. This paper proposes a study to determine the best techniques to be applied that most reduces the noise degradation. A combination of techniques can improve the results or just increase the complexity with no gain in noise elimination. An influence in the techniques sequence has also influenced the result, being necessary to determine the best sequence. Also to tune the technique parameters to the optimal, a miss tuning may preserve noise that can be removed or can eliminate precious information with the noise, degenerating the signal. The paper also aims at determining the best technique combination to be applied in parameter extraction.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127387571","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}
