The Becquerel Effect and its Adaptation to Talking Picture Systems

Rudolph Miehling

At the mention of photo-electric cells, the mind usually visualizes a glistening silver bulb that serves the magical purpose in sound projection heads of converting a varying light beam into electrical impulses that eventually reach the audience as intelligible sounds. This electrical eye finds in the flickering light beams from the celluloid ribbon, voice, music, a pistol shot, or the murmur of the sea. In visualizing this every-day magical device, we neglect to include other types of photo-electric cells that have in the distant past and may in the near future have an important bearing on the development of sound picture systems.
