About the inventions It is possible to record both transparent and non-transparent objects in holograms by feeding coherent light beam from the side. By lighting hologram with coherent light the recorded object can be seen in the space behind the hologram the way it was in reality: if it was three-dimensional it will be seen in three dimensions also in the hologram. The other image can be seen on the other side of the lighting beam and it never obstructs the main image as it was in the case with the recording method of Gabor hologram (see picture).
Implementation:
- Recording of three-dimensional objects in hologram for the needs of education and museums. By putting the film all around the object it can be seen from all sides.
- Holographic interferometry is used in the research for the measurement of vibrations and deformation in the field of mechanics. It is used for the testing of airplane tires etc.
- A sight picture produced by a hologram in an optical sight can be seen 25 meters from the sight. It is applied to small arms (pistols, guns and rifles) and is produced and sold in a free market.
