Object image optical encryption device for safety engineering, has hole apertures and detectors, which are arranged so that direction of axis of channel is irregular and also provides encryption code, where axis forms connection line

摘要

The device has hole apertures (6) and detectors (7), and optical channels attached with respective micro lenses. The apertures and detectors extracts a pixel, and are arranged in such a manner that a direction of respective axis (9) of the channel is irregular. The axis forms a connection line between lens vertex and center of the apertures and detectors. The apertures and detectors are arranged to provide an encryption code. An independent claim is also included for an encryption/decryption system with an encryption device and a decryption device.
