As a new kind of efficient, non-polluting and recyclable utilization of energy resource, Zinc-air battery has attained more and more attention in the world. The thickness of electrode is an important parameter for the quality of the battery. This thesis used Laser CCD technology in measuring the thickness of electrode. Laser CCD technology is a non-contact, high-sensitivity, high accuracy, high efficiency, it is one of the most advanced test technologies in the field of the test technology. In the detection of zinc-air battery electrode thickness, using CCD as thickness sensor, using ARM9 as the processer core, touch screen to display the data of thickness, the entire system is so highly precise, reliable, friendly and full-featured that has met the requirements of expectations.
