An occulting disk is a small disk used in a telescope to block the view of a bright object in order to allow observation of a fainter one. The coronagraph, at its simplest, is an occulting disk in the focal plane of a telescope, or in front of the entrance aperture, that blocks out the image of the solar disk, so that the corona can be seen. Starshade is one designed to fly in formation with a space telescope to image exoplanets.

dbo:abstract
  • Eine Kegelblende ist eine kegelförmige Blende, die in einem Koronografen zur Beobachtung der Korona der Sonne die Sonnenscheibe abdecken soll. Die Blende reflektiert dabei das einfallende Sonnenlicht seitwärts in den Tubus, so dass nur das Licht der viel lichtschwächeren Korona die Blende passieren kann und erzeugt damit eine künstliche Sonnenfinsternis; analog zum Mond bei einer solchen. Die Kegelblende sitzt im Brennpunkt des Teleskops und muss genau an die Brennweite des verwendeten Teleskops angepasst sein. Wegen des scheinbar veränderlichen Sonnendurchmessers während des Verlaufs eines Jahres müssen entweder verschieden große Kegelblenden verwendet werden oder die Brennweite anderweitig nachführbar sein.

  • 오컬팅 디스크는 작은 디스크(판)으로, 망원경으로 밝은 물체 주변의 어두운 물체를 관측할 때 사용할 때 도와주는 판이다. 코로나그래프가 대표적인 오컬팅 디스크를 사용한 천체 관측 기술이자 망원경이며, 외계 행성 발견에도 오컬팅 디스크가 사용되기도 한다. 자연현상으로 예를 들자면 개기일식 때 달이 오컬팅 디스크 역할을 한다고 보면 된다. (ko)
