Control over high alignment accuracy and high speed of a precision alignment system based on laser moire signals ZHOU Lizhong1, Xie Yong1, Furuhashi Hideo2, Uchida Yoshiyukl2
(1.Information Engineering School,Yangzhou Univ. ,Yangzhou 225009,China;2.Information Network Engineering Department of Aichi Instiute of Technology.Japan) Abstract：This article introdnces principle of the differential precision positioning using laser Moire signals and discusses the macro-control type and micro-control type of a precision alignment system. The principle expands the control range and effectizely shortens precision alignment time for precision alignment. It com fulfil control over high alignment accuracy and high speed of a precision alignment system.
Key Words：Laser moire signals，Control over precisioni positioning，Alignment time， Alignment accuracy
