A DCM laser dye doped Alq film serves as the active layer. High reflective and low loss electrical contacts are used to form a high quality factor coupled microcavity. Single longitudinal cavity mode is obtained at 618 nm with a threshold current density of 612 mAcm-2 under room temperature continuous wave operation. 2012 SPIE.   A fast target recognition algorithm based on MSA and MSR (EI CONFERENCE) 会议论文 2012 International Conference on Industrial Control and Electronics Engineering, ICICEE 2012, August 23, 2012 - August 25, 2012, Xi'an, China Huang J.; Wang Y.; Ji H.; Liu G. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 This paper presents a new fast target recognition algorithm  the proposed method is based on Multi-scale Auto convolution(MSA) and Multi-scale Retinex(MSR). As shown by the comparison with original MSA  it appears that this new technique solves the problem that MSA algorithm is sensitive to illumination and the computational load is significantly reduced to 1/8th of that of the original MSA algorithm  it is also robust to affine transform  light projective transform  noise  thin fog  occlusion and illumination change. the performed experiments show that it has fast searching speed  and can accurately recognize and locate target in real scenes. 2012 IEEE.   Design of Light Condenser Optical System Based on Membrane Mirror with High Power Condenser Ratio 会议论文 2012 Liu C.

Presently  for laser used as processing light source needs to amount to dozens of KW per cm2 of power density  how to increase power output and get smaller light spot for diode laser becomes a key problem. It is introduced that by designing beam shaping by ourselves and making use of optical system for beam blooming and focusing  808nm laser array composed of 20 bars eventually achieves the 1001.5w power output  coupling efficiency at 90%  11mm2 of light spot through experiments  which enables diode laser to be directly applied to cladding  welding and so on. 2012 IEEE.   Experimental study on formability of bulk metallic glass as mold for microstructure replication (EI CONFERENCE) 会议论文 Mei L.; Liu J.; Huang Y.; Lin J.; Shen J.; Tan J.; Jin P. 收藏  |  浏览/下载：38/0  |  提交时间：2013/03/25 La62Al14Cu12Ni12BMG is introduced as a substitute for silicon which was widely used as mold material for nanofabrication. For the purpose of precise microstructure replication and complete filling  effects of various imprint parameters  including imprint temperature  imprint time and compression load  on formability of La 62Al14Cu12Ni12BMG are studied and discussed. Scanning electron microscope images and results of thermal analysis are used to characterize the filling effect of La62Al 14Cu12Ni12BMG. In particular  correlations between time and thermodynamic properties are presented. Despite of its high viscosity at crystallization temperature and its narrow supercooled liquid region  La62Al14Cu12Ni12BMG is proved to be a durable and promising material which can precisely replicate the patterns of silicon mold and then transfer its own patterns on Ce 69Al10Cu20Co1BMG and PMMA. 2012 Elsevier B.V.
