Laboratory demonstration of spotlight-mode down-looking synthetic aperture imaging ladar被引量:3
《Chinese Optics Letters》2015年第9期20-24,共5页张宁 卢智勇 孙建锋 周煜 栾竹 孙志伟 李光远 刘立人 
supported by the National Natural Science Foundation of China(Nos.61275110 and 61108069);the Key Laboratory of Space Laser Communication and Detection Technology of the Chinese Academy of Sciences
We present a tabletop-scale spotlight-mode down-looking synthetic aperture imaging ladar (DL SAIL) demon- strator, which is performed by a collimator with 10 m focal length to simulate the far-field optical field. A...

Laboratory demonstration of static-mode down-looking synthetic aperture imaging ladar被引量:3
《Chinese Optics Letters》2015年第4期89-92,共4页卢智勇 张宁 孙建锋 周煜 栾竹 蔡光宇 刘立人 
supported by the National Nature Science Foundation of China(Grant Nos.61275110 and 61108069);the Key Laboratory of Space Laser Communication and Detection Technology of the Chinese Academy of Sciences
A static-mode synthetic aperture imaging ladar (SAIL) in which the target and carrying platform are kept still during the collection process is proposed and demonstrated. A target point of 0.5 mm× 0.5 mm and a two-...

Experimental research of circular incoherently synthetic aperture imaging ladar using chirped-laser and heterodyne detection
《Chinese Optics Letters》2012年第9期30-34,共5页严毅 孙建锋 金晓峰 周煜 职亚楠 刘立人 
supported by the Key Laboratory of Space Laser Communication and Testing Technology of the Chinese Academy of Sciences and the National Nature Science Foundation of China (No. 61108069)
Synthetic aperture imaging ladar (SAIL) technique belongs fully coherent processing in both the time domain and space domain and has a rather high implement difficulty. To solve this problem, the concept of circular...
