大角度低温光学扫描器

LARGE ANGLE AND ULTRA COLD SCANNER

本文介绍了低温大角度扫描器的理论特性和制作技术．我们进行了利用压电陶瓷“逆压电效应”原理在常温条件下进行大角度、可控光扫描的探索性工作，并取得了可喜的成功。

The theoretical characteristics and the manufacture technique of a novel piezoelectric optical angle scanner(PZTA)are presented in this paper.On the base of PZT′s “anti piezoelectric effect”,a new optical scanner that can be used in ultra cold environment has been developed.
