Remote users can use desktop, laptop, tablet or mobile to conduct the experiments remotely. Roles of different types of remote users have also expalined in this paper. A reliable and secure server is considered to implement the system. List of reliability and security issues cosidered to design the system is also mentioned here. Laboratories like 3D Digitization and Modeling lab, 3D Imaging and Metrology of Micro Objects lab, Face/Person Tracking lab, Optical Communications and Networks lab, Visible Light Communication lab, Lab on Laser Technologies, Lab on Infrared Technologies, Lab on Lightings and Displays, Lab on Biophotonics etc will be connected under the main server. At present, the proposed architecture is implemented at Shenzhen University; and 3D Imaging and Metrology of Micro Objects lab is connected to the main server to conduct experiment remotely which is recently tested from the University of Stuttgart, German.

The LPFG was inscribed by use of an improved CO2 laser system with an ultra-precision two-dimensional scanning technique, which produced single side periodic collapses in the micro-structured cladding of the air-core PBF. Such LPFG was utilized to measure the gas pressure with a sensitivity of -137 pm/MPa. A simulation model was built to study the gas pressure response mechanism of this kind LPFG. The stress distribution along the LPFG revealed that the outer gas pressure can lead to a stress concentration at the collapsed area and then transfer into the silica wall of the air-hole, which finally results in a shift of the resonant wavelength.","PeriodicalId":137618,"journal":{"name":"2015 Optoelectronics Global Conference (OGC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127704235","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 aims to get internal and external parameters of camera from images. Currently, classical calibration techniques are widely used in measurement and monitor, especially the method proposed by Zhang Z.Y. In this paper, it is demonstrated that classical method is rather inaccurate in some certain conditions-different distance. Experiment results on real images are analyzed. Meanwhile the method is carried out for hundreds times with different numbers of images to point out the inaccuracy of the method involved with iterative algorithm. This work provides the basis for further development in camera calibration, and plays a significant role for close-range calibration in engineering.","PeriodicalId":137618,"journal":{"name":"2015 Optoelectronics Global Conference (OGC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127814446","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}
