摘　　要：基于微型二维码标签,通过添加光学器件,给出了一种无源微型可视化光学标签系统的设计方法。该系统的发射端采用反射光的被动发光方式,接收端以普通手机相机为主体,可在相机的前端加置各种光学器件,以使其能准确探测接收微型码元图像,并实现解码。In this paper, a visual micro optical tag system of passive light source, based on micro 2D barcode, is designed by adding optical device to this system. It＇s transmitting terminal uses passive way through reflexing light and it＇s receiving terminal takes normal phone camera as the body. At the front of camera, some kind of optical device can be fixed so as the camera could detect and receive micro code image accurately and then decode it.
