Lensless Optical Encryption of Multilevel Digital Data Containers Using Spatially Incoherent Illumination

Lensless Optical Encryption of Multilevel Digital Data Containers Using Spatially Incoherent Illumination

The necessity of the correction of errors emerging during the optical encryption process led to the extensive use of data containers such as QR codes. However, due to specifics of optical encryption, QR codes are not very well suited for the task, which results in low error correction capabilities i...
