Spectroheliograph Diagram

Abstract/Description:	The principle of the spectroheliograph: Slit (1) selects some particular segment of the solar (see insert); slit (2) isolates a particular wavelength in the spectrum of that segment and allows it to impress its image upon the photographic plate. As the sun's image is made to move across slit (1), the photographic plate moves in synchronism past slit (2). Thus a photographic image of the sun, in a particular wavelength of its radiation, is composed segment by segment.
