For the purpose of mass production and quality control of ceramic bearings, we have developed an automatic measurement system using a laser scan instrument. The system includes a laser scan instrument, a conveyer platform, automatic feeders, and a personal computer. To provide precise measurement, the laser scan instrument LSM6100 was chosen because our ceramic bearings are relatively small in size. In addition, the conveyer platform is a sloped platform that conveys ceramic bearing and the automatic feeders are used to control the flow of each ceramic bearing. The experimental design includes automatic measurement software on the computer that controls all the mechanisms and records all the laser-scan readings (i.e., diameters of ceramic bearings) for data analysis. In this study, our preliminary results demonstrate that our system offers an effective solution for fully automatic and precise measurement of ceramic bearings that could be potentially used in industry","PeriodicalId":370622,"journal":{"name":"2006 International Workshop on Laser and Fiber-Optical Networks Modeling","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115257851","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}

It is proved that waveguide properties of slot determine the transmission in such gratings. For TE waves at given wavelength a minimum width of slot exists, when a considerable transmission can be achieved. For TM waves such certain minimal width does not exist, thus the considerable transmission factor can be obtained (more than 0.8 for grating with Ag) at subwavelength slot. If TM wavelength is negligible higher than grating's period, a resonance of plasmons can appear on one or two surfaces of grating. Last fact decreases the transmission factor. A spectral dependence of the transmission and the dependence of the transmission on grating's thickness are analogical to characteristics of Fabry-Perot interferometer with absorption","PeriodicalId":370622,"journal":{"name":"2006 International Workshop on Laser and Fiber-Optical Networks Modeling","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128748886","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}
