Interference possible

Japanese: 可干渉 - かかんしょう

...However, it is known that light emitted from different light sources does not produce interference fringes, and that when light emitted from the same light source is split into two and caused to interfere with each other by giving them an optical path difference, the interference fringes become unclear as the optical path difference increases, and eventually no interference fringes occur. When no interference fringes occur, the two lights are said to be incoherent, while when they do produce interference fringes, they are called coherent. The latter property is also called coherence. ...

*Some of the terminology explanations that mention "interference" are listed below.

Japanese:

…ところが，異なる光源から出た光は干渉縞を作らないことや，同じ光源から出た光を二つに分けて光路差を与えて干渉させると，光路差が大きくなるにつれて干渉縞が不明りょうになり，ついには干渉縞が生じなくなることが知られている。干渉縞を生じない場合二つの光はインコヒーレントincoherent(不可干渉)であるといい，一方，干渉縞を作るときはコヒーレントcoherent(可干渉)という。また後者の性質をコヒーレンスcoherence(可干渉性，あるいは干渉性)と呼ぶ。…
