Re: Understanding the principle
I dont need to see interference lines. I wanna know of possibility making holographic display as shown on "avatar". I think we could make holographic "object" in space if behaviors of the film and empty space in a place were film is supposed to be are simillar. Is is it so or not?

Re: Understanding the principle
I agree that fringe system is 3D, but I meant the intersection of two fronts. I see it as hyperbola.
I didn’t understand why it is impossible to demonstrate a hologram in real time? Due to air fluctuations or it is principally impossible? You didnt explain.

Re: Understanding the principle
It is not entirely clear from this figure, but I understood principal of how hyperboles are formed. If both waves were spherical, then the hyperbola would lie in the plane perpendicular to the film, and in the case of one plane wave it is in the plane of film. I got it. Is it possible to demonstrate...

Re: Understanding the principle
It seems I have imagined it correctly. Its because of spherical fronts in space they intersect each other. Ok. I have it now understood at last.

Re: Understanding the principle
Unfortunatelly I dont have mathlab. My mathlab exists only in my head. I purposely simplified process by using two-dimentional model so far as I showed in pic. I dont understand what did you mean by hyperbola? Is it projection on film? Could you explain it in detail? I couldnt understand this on how...

Re: Understanding the principle
If the red line was a film, the maximums would lie on it as I showed in picture? Is it correct? Just trying to understand how angle affects the distance.

Understanding the principle
Do I think correctly when I assume that the property of the hologram is associated with the difference in the intervals between the interference maximums registrated on the film?
