The radiometric calibration was implemented in the State Key Laboratory of Applied Optics. A standard black body source was served as radiation source. The response of the thermal imager to the input radiance was tested for different gains. The experimental results show that the average grey level of the output imaging is linear dependence of the input radiance. Because the radiance in the receiving wave range of the thermal imager is linear with the black body's temperature based on Planck's law of radiation  the average grey level of the output image is also linear with the black body's temperature after fitting a curve to the experiment data points. Then the relationship of the response and the gain was studied when the black body's temperature kept constant. The preliminary analysis of calibration data shows that the response of the thermal imager is linear and the average grey value of the image is directly proportion to the gain. According to the experimental results  the reference gains and the dynamic range of temperature measurement were obtained. Finally  the uncertainty influencing the calibration results was analyzed  the analysis shows the maximal uncertainty is 5.2%  which can meet the calibration requirement less than 10%. 2010 Copyright SPIE - The International Society for Optical Engineering.   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：16/0  |  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.
