shot noise

名詞

可算名詞 不可算名詞

A kind of noise that can be modelled by a Poisson process, originating in electronics from the discrete nature of electric charge, and associated with the particle nature of light in photon counting in optical devices.

日本語の意味

電子部品や光学機器において、電荷の離散性や光子の粒子性に起因して発生する、偶発的なノイズ現象（ポアソン過程でモデル化される）

When measuring weak optical signals with a photodiode, shot noise limits the achievable signal-to-noise ratio.

フォトダイオードで弱い光信号を測定する際、ポアソン雑音が達成可能な信号対雑音比を制限する。

意味（1）

A kind of noise that can be modelled by a Poisson process, originating in electronics from the discrete nature of electric charge, and associated with the particle nature of light in photon counting in optical devices.
