A New Age Of Invisibility Is Emerging
What is true invisibility? Basically, it’s the absence of signals that recognize specific light spectrum’s to your brain. What you see or don’t see can either physically be there or not. It’s simply up to your brain and how it’s perceived those signals.
Researchers at the University of Rochester have been tirelessly working on a new ‘digital cloak‘ that can trick your brain into thinking an object has disappeared using composite imaging.
“Invisibility cloaking makes the cloaked object appear transparent, as if the light fields exited the cloaked space without anything in it. It is a form of illusion, where light bends around the cloaked space, but re-forms afterward to appear as if it had never bent. This allows both the cloaked object and the cloaking device to not only be hidden but appear transparent.
We first make a “ray optics” approximation, where the full phase of the electromagnetic field of light is not necessarily matched (we later discuss how to remove this approximation). For imaging, whether by camera or by the human eye, the phase is typically not detectable, which is why ray tracing is usually sufficient for designing imaging devices. Ray optics cloaking can be considered a discretization of spectrum and phase for a given ray, since its phase (modulo 2) will match for one or more discrete frequencies, or discrete phase values can be matched for a given frequency. Ray optics alone significantly reduces the complexities of cloaking, such that isotropic, off-the-shelf materials can be used to build macroscopic cloaks.”(Via OSA Publishing)
Remember that hallway scene in Mission Impossible: Ghost Protocol?
”Morpheus: What is real? How do you define 'real'? If you're talking about what you can feel, what you can smell, what you can taste and see, then 'real' is simply electrical signals interpreted by your brain.- Morpheus
With the emerging VR market and non-stop CGI films, are we seeing anything real anyway?
