The Fabry-Perot pendulums are the most promising device to detect gravitational waves, and therefore the background and the internal noise should be accurately measured and reduced. In fact terminal masses generates additional internal noise mainly due to thermal fluctuations and vibrations. We propose to exploit the reflectivity change, that occurs in some special points, to monitor the pendulums free oscillations and possibly estimate the noise level. We find that in spite of long transients, it is an effective method for noise estimate. We also prove that to only retain the sequence of escapes, rather than the whole time dependent dynamics, entails the main characteristics of the phenomenon. Escape times could also be relevant for future gravitational wave detector developments.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122576808","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}

Some avionics apparatus are intolerant of failures, as lives may depend on the reliable functioning of equipment. Highly Accelerated Life Testing (HALT) is a time compression testing protocol that utilizes a step stress approach in subjecting products to varied thermal and vibration stresses. It is used to uncover design limitations and weaknesses in the preliminary design phase, helping designers to find and fix errors before they occur during the application in the field. The goal of HALT testing is to break the product by subjecting the test unit to progressively higher stress levels, incorporating thermal dwells, rapid temperature transitions, varied vibration stresses, and a combination of temperature and vibration to precipitate inherent defects. In this paper the HALT process related to an avionic equipment is described and a specific test plant is discussed.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116700263","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}
