	The research on statistical properties of TDI-CCD imaging noise (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging 2011: Advances in Imaging Detectors and Applications, May 24, 2011 - May 26, 2011, Beijing, China Gu Y.-Y.; Shen X.-H.; He G.-X. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 TDI-CCD can improve the sensitivity of space camera without any degradation of spatial resolution which is widely used in aerospace imaging devices. The article describes the basic working principle and application characteristics of TDI-CCD devices analyses the composition of TDI-CCD imaging noise and propose a new method to analyze TDI-CCD imaging noise with statistical probability distribution. In order to estimate the distribution of gray values affect by noise we introduced the concept of skewness and kurtosis. We design an experiment using constant illumination light source take image with TDI-CCD working at different stage such as stage 16 stage 32 stage 48 stage 64 and stage 96 analyse the characteristics of image noise with the method we proposed experimental results show that the gray values approximately meet normal distribution in large sample cases. 2011 SPIE.
	High power vertical cavity surface-emitting laser with high reliability (EI CONFERENCE) 会议论文 OAI收割 Optoelectronic Materials and Devices II, November 2, 2007 - November 5, 2007, Wuhan, China Changling Y.; Guoguang L.; Chunfeng H.; Li Q. 收藏 \| 浏览/下载：18/0 \| 提交时间：2013/03/25 High-power vertical-cavity surface-emitting lasers with InGaAs/GaAs quantum well active gain region are investigated. By using AlAs oxidation technology the devices have been fabricated in experiment and the characteristics of the device are carried out at room temperature. The 300m-diameter VCSELs have the maximum room temperature continuous wave (CW) optical output power of about 1.1W and the threshold current of the device is about 0.46A. The life test of the device is carried out in constant current mode. The life test of 300-m diameter lasers shows that the average lifetime is about 1800h at 80C. The device degradation mechanism is also discussed in detail.
