Cinematography with the Laryngoscope

An instrument for obtaining full-screen motion pictures of the vocal cords at the rate of 16 frames per second is described. A laryngoscope, illuminating system and viewing finder, are combined into a self-contained diagnostic unit. The problem of lighting is solved by using a quartz rod which directs the light from a small incandescent lamp to the larynx.
