The two-photon absorption cross section of rhodamine 6G in PMMA was found much larger than that in ethanol. Fluorescence properties of this kind of dye in ethanol and PMMA were also researched. The detuning of two-photon absorption for rhodamine 6G dissolved in PMMA is diminished compared with that in ethanol when excited at 800 nm. And the increase of two-photon absorption cross section of rhodamine 6G in PMMA was attributed mainly to the diminishing of detuning.","PeriodicalId":129625,"journal":{"name":"2012 International Conference on Optoelectronics and Microelectronics","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124907976","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}

On the laser communication platform, vibration effect influences on the overall accuracy and stability largely. In our platform a new vibration simulation system based on ARM is brought. In this system, the random numbers which are generated by ARM are output as a PWM (pulse width modulation) mode to drive the swinging mirror, and it causes beam jitter. The beam jitter simulates the vibration of the laser communication platform. In this platform, the spot miss distance is detected and calculated by the CCD unit. The spot miss distance is compared with the Gaussian white noise generated by ARM in real time. The result verifies that there are good consistencies between the noise and the spot miss distance. The result is similar to the typical experiment data from ESA.","PeriodicalId":129625,"journal":{"name":"2012 International Conference on Optoelectronics and Microelectronics","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129590623","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 a miniature axial flux surface mounted permanent magnet flywheel motor, using a printed circuit board (PCB) stator winding. The PCB stator has simplified the design and construction and avoids unnecessary space, since size reduction has become one of the most important aspects of flywheel motor design for nanosatellites. The performances of the machine are estimated by combination method of three-dimensional (3D) electromagnetic finite element analysis (FEA) and approximate theoretical analysis. The back EMF and electromagnetic torque are derived. A comparison between the analysis and experimental measurement results of the prototype machine is also presented. Both simulated and experimental results show that the proposed motor would be an acceptable solution for the nanosatellite applications with advantages such as simple structure and low-cost, as multi-layer circuit board production techniques have made the production of printed circuit coils cheaper and easier.","PeriodicalId":129625,"journal":{"name":"2012 International Conference on Optoelectronics and Microelectronics","volume":"os-48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127788898","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}
