Encrypted Audio Transmission Using Synchronized Nd: YAG Lasers
نویسندگان
چکیده
Encoded information based on synchronization of coupled chaotic Nd:YAG lasers in master-slave configuration is numerically studied. Encoding, transmission, and decoding of information in optical chaotic communication with a single channel is presented. We analyze the robustness of the encrypted audio transmission in a channel noise. In order to illustrate this synchronization robustness, we present two cases of study: synchronization and transmission with a single channel without and with noise in the channel. Keywords—Encryption, Secure coomunication, Chaos, Synchronization, Complex networks, Nd:YAG laser.

متن کاملLonger laser pulses for practical LII
To date nearly all LII is carried out using Q-switched, flashlamp pumped Nd/YAG lasers with pulse lengths ~10 ns. Although these lasers are well developed and readily available for use in the laboratory and in commercial instruments, they are bulky, inefficient and often the most costly part of an LII system. Cheaper, more compact lasers are becoming available, but very few are able to match th...
متن کاملIn vitro Evaluation of Dentin Surface Irradiated by Neodymium-doped: Yttrium Aluminum Garnet Laser (Nd: YAG) Using Scanning Electron Microscopy
Introdouction: Dentinal hypersensitivity (DH) is one of the most painful chronic problems reported in dental offices. Various methods have been applied for the treatment of DH. However, majority of them are either ineffective or last for a short period of time. It has been reported that lasers, particularly Neodymium- doped: Yttrium Aluminum Garnet laser (Nd: YAG), can be helpful in the treatme...
متن کاملSuccessful Treatment of Reticular Blue Veins of the Lower Eyelid by Long-Pulse Nd: YAG – Case Report with 8-Year Follow-Up
BACKGROUND Facial reticular blue veins are of esthetic concern. Most often these veins develop on the lower lids. The safest and most effective way of treatment is by vascular lasers. CASE REPORT We report on a successful reticular vein treatment using a long-pulsed 1064 nm Nd: YAG laser. We present a follow-up of 8 years with constant esthetic improvement without unwanted adverse events. C...

Introduction: In order to increase the bonding strength of the composite resin cements to the indirect composites, experiments such as the creation of surface roughness with sandblasting, acid-etching, silane application, laser, etc. have been carried out. However, there is no consensus about the results. Therefore, the purpose of this study was to investigate the effect of Er: YAG and Nd: YAG ...
