...a branch of optics that studies the state of light transmission within crystals, or the state of light reflected from the surface of a crystal. In 1669, Danish physicist E. Bartholinus (1625-98) discovered that when a thin beam of light is introduced into a cryolite crystal, the refracted beam is split into two (birefringence). Next, Dutchman C. Huygens discovered that the vibration direction of these two beams of light is biased (polarized light). ... *Some of the terminology that mentions "Bartholinus, E." is listed below.

…結晶内における光の伝わる状態,あるいは結晶の表面からの反射光の状態などを研究する光学の一部門。 1669年,デンマークの物理学者バルトリヌスE.Bartholinus(1625‐98)は,細い1本の光線を氷晶石の結晶に入れると,屈折光線が二つに分かれること(複屈折)を見いだした。次いでオランダのC.ホイヘンスは,二つに分かれたこれらの光の振動方向が,かたよっていること(偏光)を見いだした。… ※「Bartholinus,E.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
