A 3D optical inspection system can be implemented using structured light as 3D sensing technology. In this paper, we show that structured light can be projected onto the measured object by means of an innovative scanning microsystem that employs a single-axis torsional MEMS mirror for fast steering a near infra-red laser beam on a diffractive silicon microstructure. As a proof of principle of the functionality of the designed microsystem, the generated line patterns are shone on 3D objects and deformation of the projected lines is detected with a CMOS camera. From line deformation, the object depth is calculated and found in accordance to the geometrical size. The developed miniaturized solution overcomes typical drawbacks of other scanning technologies such as large size and heavy weight.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114930585","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}

ALM is a disruptive new manufacturing method by which components are created adding material layer after layer, allowing for the design and production of complex geometries, unthinkable with the use of traditional subtractive machining methods. Thinking ALM means to introduce new methodologies and software and new qualification of the whole process from raw materials to the finite part, passing through the mechanical design, the manufacturing, the post-processing, to cite a few. Concepts of reliability and degradation, together with the related models, need to be modified accordingly, whereas the choice of parameters and figures of merit to be taken into account in the numerical methods has to be carefully selected.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130733971","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 particular, the attention is focused on the antenna features obtained by means of a frustum of cone. The signal received by every column is amplified, digitally down converted and combined to form independent beams. The current configuration of the Digital Antenna Evaluator (D.Ant.E) is arranged to create 8 simultaneous beams that are enough for the purpose of the study aimed at the experimental demonstration of the functionalities of an ubiquitous radar. In particular, attention is paid to verify the antenna pattern characteristics after Digital Beam Forming (DBF) downstream of pulse compression. The benches of measurement and the adopted methodology are discussed in detail. Finally, some future objectives are envisaged in order to accomplish a full chain of signal processing up to the plot extraction and track formation. In fact, the industrial aim is the realization of a complete radar to be used for civil and military applications.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125383848","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}

Including stations on Earth, various closed paths for the pulses are possible. Time of flight measurements would be performed. The time of flight difference between right- and left-handed circuits is proportional to the angular momentum of the Sun and the detection of the effect would reach accuracies better than 1% depending on the accuracy of the clock. The four points could also be used as “artificial pulsars” for a relativistic positioning system at the scale of the solar system. Additional interesting possibilities include detection of a galactic gravito-magnetic field, retrieving information about the interior of the Sun and refining the evaluation of the influence of the quadrupole moment of the Earth and of the Sun on the gravitational time delay.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124629217","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}

For extratmosphere vehicles that have the ability to track and pursue other vehicles, due to its autonomous maneuver and high mobility, long term trajectory prediction is very difficult. In this paper, a trajectory prediction method for pursuing vehicles based on advanced guidance law recognition is proposed. With the behavioral characteristic of pursuing vehicle recognized and exploited, the proposed method is able to make long term trajectory prediction more precisely than existing methods that does not utilize guidance law recognition. Digital simulation results proved the correctness and effectiveness.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132568533","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}

Moreover, microbalances have been applied in space to perform thermo-gravimetric analyses in order to infer about the type of volatile and condensable material. When the object of contamination monitoring is an intrinsically cold surface, e.g. a radiator, an effective cooling is required to achieve the same (or slightly lower) condensing temperature. The cooling problem of the microbalance sensing area has found promising solution from the use of thermoelectric coolers, the only compact and lightweight devices that can be housed in a typical microbalance envelope. Nevertheless, performance of the thermoelectric element at low temperature is a known issue so that restricts most applications above −40°C therefore there is a lack of data about performances below that temperature and characterization in expected environment is generally required. Thus, in this work cooling performance of commercial thermoelectric elements has been assessed at low temperature along with its survival to thermal cycling in off condition, in order to assess its applicability for the space borne microbalance under development.","PeriodicalId":229414,"journal":{"name":"2017 IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123000340","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}
