TAC (time-to-amplitude converter) - TAC（时间幅度转换器）
将两个脉冲信号之间的时间差作为脉冲振幅（高度）输出的仪器。
Terahertz wave - 太赫兹波
频率约为 1 THz 的电磁波（波长：300 um）。太赫兹波能穿过纸张、木材和塑料，但不能穿过金属和水。太赫兹波段被称为物质的指纹区，随着基础研究取得的进展，它们的应用最近也在发展中。
Terminal capacitance (Ct) - 结电容 (Ct)
在光电二极管中，可将 PN 结视为一种电容器。这种电容称为结电容，是决定响应速度的重要参数。在使用运算放大器的电流-电压转换电路中，结电容可能导致增益剧增。在滨松，我们指定的结电容包括结电容加上封装寄生电容。
Thermistor - 热敏电阻
一种对热敏感的电阻，其阻值会随着温度变化而大幅改变。热敏电阻用于温度传感。
Thermoelectric cooling element - 热电制冷元件
当电流流过两个不同电导体的结点时，一侧发生吸热（或生热）现象，而另一侧发生生热（或吸热）现象。热电制冷元件利用了这种效应（称为珀尔帖效应）。反转电流方向会反转吸热和生热之间的关系。
Tiling - 平铺
两个或多个光电传感器以平铺配置排列，可具有更宽广的感光面。也称为“边对边对接”。
Tracking detector (vertex detector) - 径迹探测器（顶点探测器）
主要用于基本粒子能量物理实验的探测器，用于跟踪高能粒子碰撞产生的次级粒子的行进方向和衰变过程。径迹探测器安装在粒子碰撞点周围的位置。
Transimpedance amplifier (TIA)- 跨阻放大器 (TIA)
用于将小光电流转换为电压的放大器。放大器的增益通常以跨阻增益的形式给出，单位为伏特/安培。
Transit time - 渡越时间
电子渡越时间是从增量函数脉冲光（脉波宽度小于 50 ps）到达光阴极面到阳极输出脉冲达到其峰值振幅的时间间隔。
Transit time spread (TTS) - 渡越时间分散度 (TTS)
渡越时间分散度是 PMT 内不同的电子轨迹和离开阴极的光电子的不同初始速度所致。其影响是渡越时间波动或抖动以及脉冲增宽。分散度定义为这些波动概率分布的 FWHM。
Transition frequency - 转移频率
最初表示发射极接地的晶体管的电流增益率 (hfe) 为 1 时的频率，但现在表示放大元件的增益率变为 1 时的频率。
Tunable laser - 可调激光器
多波长传输系统的光源。
