Intensity interferometry

...In the 1970s, attempts were made to revive this method by incorporating new technological advances. Other methods for measuring the apparent diameter of a star include intensity interferometry, in which the light from the star is received by two concave mirrors, amplified by a phototube, and the correlation between the output intensities of the concave mirrors is measured; speckle interferometry; and a method using a stellar occultation by the moon. [Takashi Tsuji]...

*Some of the terminology that refers to "intensity interferometry" is listed below.

…70年代になって新しい技術的進歩をとり入れてこの方法の再生が試みられている。恒星視直径の測定には，このほか星からくる光を二つの凹面鏡で受け，光電管で増幅し各凹面鏡の出力強度の相関を測定する強度干渉法，スペックル干渉法，月による星食を用いる方法などがある。【辻 隆】。…
