1) dark current noise
暗电流噪声
1.
TDI-CCD noise mainly comes from two ways,one is TDI-CCD proper noise,such as photo shot noise、non-uniformity noise、dark current noise、fix pattern noise、transfer noise and so on,the other is TDI-CCD noise interference in work process,such as reset noise and 1/f noise.
TDI-CCD的噪声主要来自两个方面,一个是TDI-CCD器件本身所固有的噪声,如霰粒噪声、非均匀性噪声、暗电流噪声、固定图形噪声、转移噪声等,另一个是TDI-CCD工作过程中的各种噪声干扰,如复位噪声和1/f噪声等。

补充资料：暗电流
分子式：
CAS号：
性质：光度计的光电元件，当没有光照射在光阴极上时，流过的背景电流。它干扰微弱光信号的测量，并与环境温度有关，故在手动单光束仪器中每次测量均需加以校正。
