To reconstruct a radiation environment, we proposed an information fusion method based on images from a gamma camera and an RGB-D (Red Green Blue-Depth) camera. First, on a mobile base, the reconstruction platform is presented to integrate gamma imaging with RGB-D information. Secondly, the dense point cloud map of the environment is formatted with VSLAM (Visual Simultaneous Localization and Mapping) based on an RGB-D camera. Thirdly, from the gamma camera images, the radioactive contour feature is extracted to localize the source right ahead cameras, and the radiation area point cloud is obtained using the relative position of the two cameras. Lastly, the whole radiation environment map is generated with point cloud fusion, and the source position is estimated with the minimum bounding box. To validate the efficiency of this method, a laboratory room with one 152Eu source is reconstructed under above fusion platform. In the experiments, three feature objects are selected, and their size are calculated based on the cloud point. Also, in two scenes with the same size in released literature, the sources are localized. Although there exist some errors, comparisons show that this method performs well and keeps at low deviation level.","PeriodicalId":289132,"journal":{"name":"2021 IEEE 15th International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121765231","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 traditional test method based on sinusoidal fitting has high test accuracy, but the test time is long, which limits its application in practical test. The sine wave fitting algorithm based on maximum likelihood estimation (ML) can better take into account the test accuracy and test efficiency, and has a good application prospect. This paper mainly studies the optimization of ADC test algorithm based on maximum likelihood estimation. Firstly, the ADC conversion level is obtained by the parameter spectrum estimation method. When the conversion level is used as a known parameter, the accuracy and speed of the algorithm are guaranteed. The initial frequency is estimated by the frequency estimation method, and the signal parameters and noise standard deviation are estimated by the three parameter sinusoidal fitting method. After improvement, only one data acquisition is needed to test the dynamic and static parameters of high-speed and high-precision analog-to-digital converter, such as INL, SINAD, ENOB, etc. Through simulation and test, the test time is shortened on the premise of ensuring the test accuracy, and the test efficiency of high-speed and high-precision ADC is improved. It has great practical value.","PeriodicalId":289132,"journal":{"name":"2021 IEEE 15th International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120978874","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}

FBG has the advantages of small size and light weight in flight test applications, but the optical fiber is easily damaged, so it is necessary to use a stainless steel substrate to encapsulate the optical fiber and then use AB glue to bond to the test substrate. In this paper, FBG and resistance strain gages are compared to verify the feasibility of strain measurement. The results show that the response trend of the FBG sensor is consistent with the resistance strain gauge, but there is a large strain loss in the bonding layer of the FBG after packaging. Further establish a strain transfer model for simulation analysis, and quantitatively calculate measurement error. It is proposed that under the premise of meeting the feasibility of flight test process, the thickness of the cement layer should be small enough and the elastic modulus should be large enough, which can effectively improve the accuracy of FBG strain measurement.","PeriodicalId":289132,"journal":{"name":"2021 IEEE 15th International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124033803","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}

Hence, there is a clear need for more sophisticated methods for testing and estimating the performances and reliabilities of microprocessor. This paper presents a set of Hardware/Software co-design hardening design techniques to realize the systemic reliability design related to the high security commercial microprocessors with Hercules ARM Cortex-R4F, which are applied to the inter-satellite communication missions. Then these techniques are used to fulfill the radiation harden design from sensitive units of signal event effect for system layer, as well as the latch-up current self-monitoring and recovery design. Ultimately, through the construction of the heavy ion irradiation test evaluation system, the microprocessor being tested is immune to heavy ion induced by single event latch-up and single failure interrupts show a very low response. Thus, the device depended on the radiation harden design is defined as a high reliability and security candidate for digital process system in space applications.","PeriodicalId":289132,"journal":{"name":"2021 IEEE 15th International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123015448","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}
