This reveals new ways of improving the performance or enriching the functionality of the system, while at the same time causing certain difficulties in system analysis and assembly. To overcome this, we present a physical-optics-based simulation approach. It starts from an electromagnetic representation of sources, which enables the modeling of coherence and polarization. We demonstrate how to integrate new components (from microscopy objectives to diffractive, micro- and nanostructures) in selected classical interferometric setups, and gauge whether the resulting system fulfills the desired functionality.","PeriodicalId":219169,"journal":{"name":"Photonic Instrumentation Engineering VI","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116802877","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}

Pickrell, B. Risch, S. Rountree, Matthew Davis","doi":"10.1117/12.2507001","DOIUrl":"https://doi.org/10.1117/12.2507001","url":null,"abstract":"In the nuclear industry, there is a need for sensors that are resistant to both high temperatures and radiation. Fiber Bragg gratings inscribed into radiation resistant fibers are a potential solution to this as the femtosecond-infrared laser can inscribe Bragg gratings into fibers without a photosensitive core. In order for these gratings to be used for sensing, they need to be characterized to determine their temperature and radiation response and sensitivity. This paper characterized three commercially available fibers for use in high heat and high radiation environments. There are six fiber variants examined in this study. Three basic fiber designs are investigated: a germanium doped core, a germanium doped core with fluorine cladding, and a fluorine doped core and cladding. For each fiber design, normal and pre-irradiated versions are investigated. The fibers were tested for thermal response by heating them to 1000C and holding for 24 hours, and for radiation resistance by irradiating with gamma radiation. The germanium core doped fibers were more resistant to thermal effects but still had a wavelength shift during the 24-hour soak. The fluorine-doped fibers either had the gratings partially or completely erased during the thermal hold at 1000°C, but showed suitability for short term excursions to this temperature. The radiation data showed significant shifts in some cases, but there was not enough data to form a definitive conclusion. It appears that radiation introduces variability in the response of the Fiber Bragg Gratings (FBG).","PeriodicalId":219169,"journal":{"name":"Photonic Instrumentation Engineering VI","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116322965","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}
