Chapter 4 平面、棱镜及光学材料 Fraunhofer lines Joseph von Fraunhofer The lines were originally observed as dark features (absorption lines) in the optical spectrum of the Sun. The English chemist William Hyde Wollaston was in 1802 the first person to note the appearance of a number of dark features in the solar spectrum. In 1814, Fraunhofer rediscovered the lines and began a systematic study and careful measurement of the wavelength of these features. In all, he mapped over 570 lines, and designated the principal features with the letters A through K, and weaker lines with other letters It was later discovered that each chemical element was associated with a set of spectral lines, and deduced that the dark lines in the solar spectrum were caused by absorption by those elements in the upper layers of the Sun. Some of the observed features are also caused by absorption in oxygen molecules in the Earth's atmosphere. Engineering Optics Dr. F. Guo Qingdao TECH Spring 2012
