Depending on the proposed information carrier’s pixel size, different readers can be used. For example, pixels larger than 500 um x 500 um size can be easily readable by a cell phone camera, while small features can only be read by high resolution camera sensors or optical scanners. The covert IR data stored on the nano-substrate remains hidden under normal light conditions. To read the covert data, an IR sensitive filters plus an edge-pass IR filters need to be used.
Having data stored in multiple IR wavelengths (multispectral IR sub pixels) may make the reading process time-consuming since separate IR filters will be needed to read the data one wavelength at a time. We investigate the retrieval of information simultaneously and rapidly. We have developed such multispectral optical filters working with a camera for biomedical applications and we experiment and adapt them to NanoMedia.
