Terent'ev Yu.I. Suppression of light diffraction at the relative index of refraction close to unity. Part II. // Atmospheric and oceanic optics. 2007. V. 20. No. 11. P. 873-879. Copy the reference to clipboard
The light diffraction on a screen is almost completely suppressed by decreasing the relative refractive index to unity in the case, when the screen is made of optically absorbing glass plates (SS8, TS2, TS3, NS12) located in different liquids.
