Light pulses of half-width T = 5 x 10-9s were obtained with this rotating mirror system, the repetition rate of pulses being n = 4.6 × 103s -1 and the energy of a single pulse 8 × 104 electron-volts. Due to effects resulting from the extremely high speed of the rotating mirror, reflecting layers of
We present a basic optical encryption architecture that admits several cryptography applications based on multiplexing. Users can decrypt different private images from the same encrypted image, a superuser can have a key that decrypts all encrypted images, and multiplexed images can be encrypted wit
