If I could have plunged into a
light wave and been transported instantaneously to Dona Rita's door it would no doubt have saved me an infinity of pangs too complex for analysis; but as this was impossible I elected to walk from end to end of that long way.
The body of the steward was seen slowly to disappear, as was expected; but when the
light waves, which had been raised by his fall, began to sink in calmness, and the water finally closed over his head, unbroken and still, a very different feeling pervaded the spectators.
The first step is to record the
light wave information of the object using the principle of interference, namely, the shooting process: the objects shot forms a diffuse object beam under laser irradiation; the other part of the laser is emitted on the holographic film as a reference beam to be superimposed with the object beam to generate interference, and the phase and amplitude of each point on the object
light wave are converted into spatially varying intensity, thereby recording all the information of the object
light wave by utilizing the contrast and spacing between the interference fringes.
According to the researchers, different colours of an incoming
light wave must follow different paths as they travel through a conventional cloaking device around an object, and because these different colours take different amounts of time to traverse the cloak, an easily-detectable distortion is produced that gives away the presence of the cloak, and thus the object.
As soon as this propagation occurs, the filter restores the
light wave to its original state.
The spectral cloak operates by selectively transferring energy between certain colours of the
light wave.
In this setup, a holographic image of the object is created by
light wave interference between the incident beam and laser light reflecting off the object.
It provides the principles of digital communications in the context of optical and photonic transmission technology and the principles of noise generated in electronic, optical, and photonic processes, including the sensitivity and quantum limits of such modulated
light wave systems, as well as presenting the noise effect on optical transmission of various modulation formats over optically amplified fiber links and identifying the roles of the generated noises in photonic amplification processes.
The mirror works by reversing the direction of motion of each
light wave while preserving the wave's original shape.
