System having optically encoded information |
摘要 |
A optical system having optically encoded information includes a microptic multiplet (MOM) optical system on compact arrays or cards for both secure (encrypted) and non-secure applications where the presence or position of optical micro-lenses is indicative of the encoded information. The system is characterized by a first microptic lens module (MLM) that has data optically encoded thereon based on the position of a lenslet in a lenslet cell. One or more additional microptic lens modules can be used as a key(s) to interpret the data.
