MBE (molecular beam epitaxy) - MBE（分子束外延）
一种外延生长技术，通过在加热的基板晶体上提供由晶体组成元素构成的分子束来形成薄膜晶体，这些分子束是在超高真空中蒸发单独单元的每个元素而产生的。
MCA (multichannel analyzer) - MCA（多通道分析仪）
将多个输入脉冲的高度显示为直方图的仪器。
MEMS (micro-electro-mechanical systems) - MEMS（微机电系统）
MEMS 是将电子电路与微执行器、微型机构和微传感器等集成在一起的系统，采用精细工艺技术制造。
Microfocus X-ray source - 微焦点 X 射线源
这是焦点非常小（微米级）的 X 射线源。微焦点 X 射线源可以捕获清晰、锐利的放大 X 射线图像，因为即使放大也能抑制边缘模糊。
Minimum sensitivity - 最小接收灵敏度
获取一定水平内的误码率所需的最小光输入功率。最小接收灵敏度取决于传输比特率、所需的误码率、用于测量的伪随机码的类型以及消光比等。
MOCVD (metal organic chemical vapor deposition) - MOCVD（金属有机化学气相沉积）
一种外延生长技术，通过在加热的基板晶体上对以蒸汽形式提供的有机金属进行热分解和化学反应来形成薄膜晶体，这些有机金属在常温常压下是固体或液体。
Modulation transfer function (MTF) - CCD - 调制传递函数 (MTF) - CCD
调制传递函数 (MTF) 常用于量化以场景的某个空间频率再现对比度的图像传感器的分辨率。由于 CCD 的受光面由离散像素组成，因此它表现出由基于离散采样定理的奈奎斯特极限决定的极限分辨率。例如，当使用 CCD 查看黑白图案时，黑白信号电平之间的差异会随着图案的精细而减小，最终达到无法解析图案的程度。理想的 MTF 表示如下：$$ MTF = sinc \biggl( \frac{\pi \cdot f}{2 \cdot fn} \biggr) $$ 其中 f 和 fn 分别是场景的空间频率和空间奈奎斯特频率。
然而，由于创建光学正弦波比较难，通常使用提供矩形波的测试图案。在这种情况下，将空间频率特性称为对比度传递函数 (CTF)，以与 MTF 区分。（请注意，CTF 可通过傅里叶变换转换为 MTF。）
实际 CCD 分辨率取决于信号电荷在硅片内部聚集之前发生的扩散程度。当入射光子在耗尽层内被吸收时，生成电荷不会扩散，而是被相应的像素收集。因此，分辨率不会劣化。换言之，分辨率取决于硅片内吸收入射光子的深度。入射光子波长越长，分辨率劣化越严重。
MOEMS (micro-opto-electro-mechanical systems) - MOEMS（微光机电系统）
使用 MEMS 技术的光学系统。也称为光学 MEMS。
MOST (Media Oriented Systems Transport) - MOST（媒体导向系统传输）
主要用于欧洲车辆的车载网络标准。这是一种使用 POF（塑料光纤）的环形网络，其节点间通信速度为 25 Mbps 和 150 Mbps。除了车载用途外，MOST 还用于机场的对讲机网络等。
MPP (multi-pinned phase) operation - MPP（多针相位）操作
MPP 是一种操作模式，其中构成 CCD 电极的 MOS 结构门下的所有 CCD 通道都是反向的。该模式也称为反向操作，并可减小暗电流，因为它极大地抑制了硅和二氧化硅界面处热激发电子的生成。
Multimode fiber - 多模光纤
用于以多横模（电磁场分布）传输光的光纤。多模光纤不适合长距离传输，因为传输的波形会由于信号光到达时间的差异而失真，具体取决于模式（模态色散）。与单模光纤相比，芯径较大，因此很容易连接到光发射器。然而，很难将光束凝聚到用于高速通信的光接收元件上，因为该元件必须具有很小的光接收区域。
Mu metal
由高介电常数合金制成的屏障。它用于屏蔽光电倍增管，使其不受磁场影响。
