Network management systems must solve complex problems in routing and wavelength blocking, path verification, and more as the photonic layer assumes some of the tasks previously handled by higher layers.
When a plane wave with a correct wavelength illuminates the optical verification system, the corresponding image is extracted to display on the output plane.
Compared with the previous encryption and verification technique, these predesigned wavelengths can be used as additional verification keys, which should significantly enhance the security of system.
The other key technologies include impedance matching for optimal signal transportation and near-infrared wavelength selection for improving the acquisition signal sensitivity in verification tests aiming at smile versus calm.
Through comparative analysis and real network verification, it is concluded that the CWDM multi wavelength scheme is a recommended scheme to meet the real network reconstruction.
Here we provide a more thorough experimental verification of this model by variation of the excitation wavelength, light intensities and mediator concentrations.
Only when all the frames of images recorded by different wavelengths are obtained, the user can then pass through the verification procedure.
We propose a new optical encryption and verification technique in which multiple frames of images recorded by different wavelengths can be synchronously encrypted into double pure phase masks (PMs).
In ground based experiments (experiment verification tests), the following space parameters were simulated and studied: temperature, vacuum and short wavelength UV (UV-C, down to 200 nm) radiation.
