Meteor camera - Ryusei camera (English name)
|
Starting in the 1930s, Harvard Observatory and other institutions began to make specialized attempts to photograph meteors, and specialized cameras were developed. These consisted of a rotating fan-shaped disc placed in front of the objective of the wide-field Super Schmidt Telescope, which interrupted the trail of a meteor every 1/60th of a second, capturing the image as a broken line.

1930年代よりハーバード天文台そのほかで，流星を専門に撮影する試みが始り，専門の写真機がつくられるようになった。これは広い視野をもつスーパー・シュミット望遠鏡の対物鏡の前に回転する扇形板を置き，流星の軌跡が 60分の1秒ごとにさえぎられて破線状に写るようになっている。
