If our usual sight is capable to see a beam "axion field", there is a desire to photograph this beam. But, alas, even to photograph air mirage above a heated object is not simple. It is even more difficult to photograph a beam "axion field".

In our case, it is not be use already habitual for physicist's a method of photography of optical inhomogeneities in interferometers. First, the beam "axion field" refracts light not systematically, casual fashion. Secondly, apparently, light refracts resonant. As we no know resonant lengths of waves of light, it is better to use white light, instead of monochrome light of the laser in an interferometer.
For photography of a beam "axion field" of the generator G (see Fig.1) is possible to use a shadow method. In this method, the parallel stream of light is transparent a beam "axion field", and is focalized by a lens L1 (see Fig.1) in a point of focus O1. In a point of focus O1 the small absorbing barrier E is located which completely overlaps a stain of light in this focus. Light scattered by a beam "axion field" in a point O, is focalized by a lens L1 in a point O2 outside the absorbing barrier E and then is focalized on the screen/photographic plate S by a lens L2. Thus, on the screen/photographic plate S we shall see only light scattered by a beam "axion field". We shall have a photo of a beam "axion field". The shadow method is good only in laboratory requirements. It is more interesting to try to use a method of an optical tomography, to which the parallel stream of light is not necessary.
In usual object-glass of cameras the purpose of achievement maximum of the depth of sharpness is pursued. In an optical tomography the purpose opposite - is necessary to achieve the minimal depth of sharpness of a lamina of viewed object and cut off light, which radiates from objects outside of this lamina. This problem successfully is solved a human eye an observing beam "axion field". And this problem is not capable to solve the usual camera.
For an optical tomography it is possible to use the design, which is shown in a Fig.2. Light scattered by a beam "axion field" of the generator G in a point O, is transmuted into a parallel stream of light by a lens L1. Then the parallel stream of light transits through a package blacken, of long, thin tubes T and is focalized on the screen/photographic plate S by a lens L2. Light scattered in points nearer or further than point O will not formed a parallel stream of light after a lens L1 and will be absorbed blacken by walls of tubes of a package T. Thus, we can descry layer wise thin structure of a beam "axion field", changing a focal distance of a lens L1. Instead of a package of tubes T it is possible to use special glass (I do not remember its name), which is quasi welded from set of glass optical fibrils with blacken a surface. Such glass is transparent, if our sight is perpendicular surfaces of a glass and is opaque, black under other angle. This glass is usually used in devices of night vision and some spectrometers.
Instead of a package of tubes and special glass it is possible to use a package from several stratums of a grid with the combined meshes. Instead of a grid it is possible to use a color separation mask from a colour television tube. Certainly, the description of methods is simplified. Some experience of operation with optical instruments is necessary for embodying the described constructions.
