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，并在此基础上研究出了能在液氮环境下进行大角度扫描的低温扫描器 This article describes the low-temperature high-angle scanner theoretical characteristics and production technology. We conducted a exploratory work using the principle of “inverse piezoelectric effect” of piezoelectric ceramics to conduct large-angle and controlled light scanning under the condition of normal temperature and achieved gratifying success. On the basis of this, Low temperature scanner for high angle scanning under the environment
