The square can then be placed on an item using adhesive or woven onto items such as the canvas of paintings. A electron-beam lithograph drills into the plastic face of the microscopic square which will be the future 3D code. It talks about placing microscopic 3D barcodes on valuable works of art, jewels, and other precious items, which can then identify them if they are even stolen. This is an interesting, but older article on 3D barcode technology being used to identify stolen valuables. Those types of scanners normally read the white space between the barcode lines to decode the barcode. DPM readers only read the height variances of the barcode, therefore there is no need to make the barcode black and white as most other barcodes are. A direct pat mark barcode reader contains a laser like the ones that are contained in home and office scanners that scan pictures or documents in a computer. The labeling of parts with 3D barcodes is called direct part marketing or DPM. Once the scanner scans the 3D barcode the result read by the height of the lines is interpreted. As you can see from the different dimensions involved in different type of barcode making and the formula involved in reading 3D barcodes, there is a lot of basic physics knowledge involved in their creation and decoding. The 3D barcode scanner uses a laser that calculates the height of the barcodes lines based on the distance and time it takes for the laser to read it. Other types of barcodes are read by the variances in reflected light as the light scans the code. Unlike 1D and 2D barcodes, the bars in a 3D barcode are read by a scanner that reads the differences in the height of each line. Therefore a 3D barcode is usually engraved on a product or applied on a product so that the barcode has depth and thickness.
To solve this problem they discovered a new way to track their parts in the manufacturing system by using 3D barcodes.Īs I explained earlier in the article on the difference in dimensions, three dimensional objects must have thickness and must be measurable on the x, y, and z-axis. These manufacturing companies could not just use a regular barcode that is normally printed on paper or a sticker, because of the high temperatures, chemicals, and solvents that would easily destroy a barcode. Many manufacturing companies needed a barcoding system much like the UPC barcodes used in stores to track purchases and store product information.
