In 1941, Soviet inventor Semyon Pavlovich Ivanov published a two-page technical report in an issue of American Cinematographer describing the development and theatrical application of a so-called raster screen, also known as a parallax stereogram, in the Soviet Union, inciting international attention about this technology that would last for decades. The raster screen made autostereoscopic viewing of three-dimensional films in theatres possible. In other words, audience members could perceive stereoscopic effects without having to wear specialized glasses.
