Piezoelectric tube scanners are thin cylinders of radially poled piezoelectric<\/a> material with four external electrodes and a solid or quadrant internal electrode. When a voltage is applied to one of the external electrodes, the actuator wall expands which causes a vertical contraction and a large lateral deflection of the tube tip. A circumferential electrode can be used for vertical or radial extension and contraction.<\/p>\n \u7531\u56db\u4e2a\u5916\u7535\u6781\u548c\u4e00\u4e2a\u56fa\u4f53\u6216\u8c61\u9650\u5185\u7535\u6781\u7ec4\u6210\u7684\u5f84\u5411\u6781\u5316\u538b\u7535\u6750\u6599\u7ec4\u6210\u7684\u8584\u5706\u7b52\u3002<\/p>\n \u5f53\u7535\u538b\u65bd\u52a0\u5230\u5916\u90e8\u7535\u6781\u4e4b\u4e00\u65f6\uff0c\u81f4\u52a8\u5668<\/a>\u58c1\u81a8\u80c0\uff0c\u5bfc\u81f4\u7ba1\u5c16\u5782\u76f4\u6536\u7f29\u5e76\u4ea7\u751f\u8f83\u5927\u7684\u6a2a\u5411\u504f\u8f6c\u3002\u5706\u5468\u7535\u6781\u53ef\u7528\u4e8e\u5782\u76f4\u6216\u5f84\u5411\u62c9\u4f38\u548c\u6536\u7f29<\/p>\n \u5e94\u7528\u8303\u56f4\uff1a\u626b\u63cf\u63a2\u9488\uff0c\u663e\u5fae\u955c<\/a>\uff0c\u5149\u7ea4\u62c9\u4f38<\/a>\uff0c\u5149\u7ea4\u626b\u63cf<\/p>\n
