【摘要】 介绍了本实验室针对阵列扫描激光三维成像所涉及的关键技术所开展的前期研究成果。首先介绍了阵列扫描激光三维成像系统结构。其次开展了阵列激光照明与视场匹配实验效果验证,验证了阵列照明与成像的可行性。介绍了阵列成像光电信号处理过程及并针对阵列计时关键技术进行了实验测试,可实现64路优于140ps的计时分辨率。最后搭建了阵列激光三维成像实验验证平台,对阵列信号处理部分进行了实验评估,实现了基于阵列的无扫描三维成像功能,可获得20cm的距离分辨率。更多还原

【Abstract】 Some research results about 3D imaging based on array scanning carried out at our laboratory are introduced. At first the array scanning system structure is presented. Then array illumination and field of view matching is evaluated. The procedure of optical-electrical signal processing and multi-channel time to digital conversion technique are introduced and tested, which demonstrated a timing resolution of 140 ps. Finally a 3D imaging experiment based on array detector is designed and come to a range resolution of 20 cm.更多还原
