Abstract

We show an optical system of micro visual tag which is based on the principle of microscope and the property of QR Code. Unlike current optical tag, such as barcodes, must be read within a short rang and occupy valuable physical space on products, the new tags can be shrunk to several millimeters and captured from a distance of over 0.5 meters. We design the transmitter according to the parameters of camera lens. We also take the detection range and apertures into account, meanwhile conduct simulations and experiments. The result shows that: the tag can be captured from a long distance, and the amplified image is able to accurately be decoded.
