Would someone, PLEEEEAAAASSSEEE, explain here how holography actually works.
...I mean - I know (I've already read about it times and times again) - I know it has to do with interference patterns (interaction between two components of light (object and reference light)), I see it has to do with difraction (the characteristic of light that it can diverge path if the "hole" is comparable to the wavelength (...or something))... and phase of light (actually what is the definition of "light phase"?!?), and coherence of the light itself (ability to interfere (with itself))...
I've tried to find an essential explanation about how holography ACTUALLY works on many places (unsuccessfully every time) - still I can't quite figure it out... (and it seems interesting enough (and more!) to bother myself with this even further) I tried to find topics about it even on this forum - no luck...
Can someone give a full and definite explanation please?
(no mathematic formulae, just an explanation on how things LOOK like - there on a holographic plate - in relation on how it creates a diferent picture depending on an angle of view)
I mean - what all those things have to do with the fact that you view a different intensity of light on some/any point of the (two-dimensional) plate of a hologram?!?
Is starting with the physical apearance of the surface of the holographic film under strong enough microscope a good way to explain how it all works?
PS: have you seen those true color holograms!? That stuff is amazing! (Imagine that you have a true color FULL ZIZE holographic picture of yourself, put it there on your wall - so it looks as if the picture is actually a door to another room - and there you stand (wow! generations to come could ACTUALY see EXACTLY how you looked like - THE original of yourself! Wow, wow, wowy, wow...))
