Latest Patents

Virolainen holds a patent titled "Differential phase voxel symbol determination." This invention involves a differential voxel symbol reader that is configured to detect phase or polarization changes in a probe light beam. These changes occur due to interactions with voxels distributed in an optical storage medium, which are designed as light-scattering nanostructures. Instead of determining an absolute change in the state of the probe signal, the invention detects a relative change by comparing the probe light beam against an orthogonally-polarized reference light beam. This method effectively cancels out the effects of light scattering and other impairments, thereby improving the accuracy of the reading process.
