Research on the application of DVD pick-up head in three-dimensional optical storage Jianwen Cai a, Fei Meng, Yafeng Zhang, Meifeng Zhang, Xuetao Pan School of Photoelectric Engineering, Changzhou Institute of Technology, Changzhou,China,213002 a caijw@ustc.edu.cn Key words: information optics, three-dimensional optical storage, DVD pick-up head, DVD servo technology Abstract： Two-photon three-dimensional optical data storage is an effective method for high capacity data storage.
When information read out, for two-photon photobleaching material, using 800nm ​​light pulse, passes through two-color film and DVD pick-up head, and focuses on the selected channel. the excitation fluorescence signal passes through DVD pick-up head, two-color film, color filters, confocal pinhole lens and the photomultiplier tube (PMT). this optical path adopts confocal imaging technique, has a simple optical system and high axial resolution, reduces crosstalk between the storage layers and eliminats the caused background effects of inhomogeneity of the storage media and substrate, the data signal is collected by the PCI-7484 data acquisition card.

The use of Compound Cooling Holes for Film Cooling at the End Wall of Combustor Simulator Nor Azwadi Che Sidik1, a and Shahin Salimi2, b 1Faculty of Mechanical Engineering, Universiti Teknologi Malaysia, 81310 Skudai, Johor Bahru aazwadi@fkm.utm.my, bsshahin2@live.utm.my Keywords: Film cooling, Compound cooling holes, Dilution holes, Combustor endwall, Cylindrical cooling holes.
Introduction Continuous improvements in the performance of film cooling, as well as various internal and external cooling techniques, are utilized to reduce the temperature of blade material below its melting point.
The film-cooling simulation presented that the plenum inflow condition provided a mean steady state at the coolant ejection positions, and a good match of the key quantity of film cooling (i.e. cooling effectiveness) was obtained between simulation and experiment.
