The measurement of target's surface temperature is the foundation of infrared radiation characteristics measurement. The principle and configuration of target's surface temperature measurement system based on colorimetry is introduced  the measurement model is deduced and the processes of temperature measurement are presented. Least-square method and back-propagation neural network method are both used to deal with the demarcating data. Compared with the least-square method  Back-propagation neural network has more advantages  such as high precision  good applicability and so on.   衍射透镜焦斑的非迭代相干检测研究 学位论文 作者:  王松贤 收藏  |  浏览/下载：37/0  |  提交时间：2018/12/26 衍射透镜  diffractive lenses  数字全息  digital holography,  微光器件  micro-optical device,  光子筛  photon sieve,  自动对焦  autofocus
