Remote-sensing technology plays an important role in military and industrial fields. Remote-sensing image is the main means of acquiring information from satellites, which always contain some confidential information. To securely transmit and store remote-sensing images, we propose a new image encryption algorithm in hybrid domains. This algorithm makes full use of the advantages of image encryption...
The nonlinear optical properties and photoinduced anisotropy of an azobenzene ionic liquid–crystalline polymer were investigated. The single beam Z-scan measurement showed the polymer film possessed a value of nonlinear refractive index n 2 =−1.07×10 −9 cm 2 /W under a picosecond 532nm excitation. Photoinduced anisotropy in the polymer was studied through dichroism and photoinduced...
