F
Fano factor - 法诺因子
通过入射辐射在晶体中生成的电子空穴对的平均数量 (J) 由以下公式表示：$$ J = \frac{E}{ε} $$ E：辐射能量
ε：生成电子空穴对所需的平均能量
在这种情况下，表示电子空穴对数量的统计波动的标准偏差（σ：法诺噪声）由以下公式表示：$$ \sigma = \sqrt{FJ\ } $$ 公式中的 F 是用于校正与帕松分布的偏移的系数，称为法诺因子。
FDA (floating diffusion amplifier) - FDA（浮动扩散放大器）
最常用于 CCD 输出部分的低噪声读出方法。滨松 CCD 使用此 FDA。
Fill factor - 填充因子
这是“不包括配线部分等的光电二极管面积” 与像素面积的比值。
Flip-chip bonding - 倒装芯片接合
一种将芯片倒置在封装或另一个芯片上进行电气连接，从而将芯片与连接到芯片上表面上电极的凸块（金属突起，如焊料）接合在一起的技术。芯片对芯片贴装允许更小的组件。
Frequency response - Image intensifier - 频率响应 - 图像增强器
这表示从荧光屏产生光发射度所需的输入照度，等于当光阴极面上的输入照度为零时获得的输入照度。这表示图像增强器的固有背景水平或可检测照度的下限。
FTTH (fiber to the home) - FTTH（光纤到户）
这是一个正在进行的计划，通过使用光纤作为从电话局延伸到每个家庭的电话用户线路，来构建高速宽带数据通信环境。FTTH 被视为用光纤取代所有用户线路的最终目标。根据进展阶段，实现该目标的各个步骤如下：FTTZ（光纤到小区）、FTTC/FTTP（光纤到路边/光纤到人行道）和 FTTA/FTTB/FTTO（光纤到公寓/光纤到楼/光纤到办公室）。
Full well capacity - 最大阱容
CCD 的饱和电荷量相当于可转移到相邻电位阱的信号电子数，因此也称为最大阱容 (FW)。饱和电荷量或最大阱容以电子数 (e-) 表示，特别是用于科学应用的 CCD。
CCD 的最大阱容由以下四个因素决定。
- 1. 垂直移位暂存器饱和度（垂直最大阱容）
- 2. 水平移位寄存器饱和度（水平最大阱容）
- 3. 总阱饱和度（总最大阱容）
- 4. 输出部分饱和度
在 CCD 面阵图像传感器应用中，每个像素的信号电荷单独输出，因此饱和度由垂直最大阱容决定。另一方面，水平最大阱容设计为在高于垂直最大阱容的水平下饱和，以实现线 binning（增加垂直像素信号）。总最大阱容由求和门（即最后的时钟脉冲门）形成，设计为大于水平最大阱容，以添加来自水平移位寄存器（像素拼接）的信号。
因此，作为电压导出的输出信号的饱和电压 Vsat 通常由以下公式给出：$$ Vsat = FW \cdot Sv. $$ $$ Sv(转换\系数) = \frac{uV}{e^-} $$
FWHM (full width at half maximum) - FWHM（半峰全宽）
用于描述正态分布（高斯分布）的宽度。FWHM 是正态分布半 (1/2) 最大值的全宽。
