TeraFlash smart
超快时域太赫兹平台
- 快速测量完整太赫兹波形: 1600 脉冲 / 秒
- 专利 ECOPS 技术
- 坚固的设计，无机械延迟线
- 时域动态范围: 50 dB < 1 ms, > 80 dB 1 s内
- 光谱带宽：3THz<1ms, 4THz 1s内
TOPTICA TeraFlash smart系统采用名为ECOPS（"Electronically Controlled OPtical Sampling"，即电子控制光学采样）的专有方案。该系统包括两个同步飞秒激光，无需机械延迟。这使得超高速测量成为可能：TeraFlash smart系统每秒可识别1600个完整太赫兹波形，可以前所未有的高速度实现太赫兹厚度测量。因此，该系统可用于测量快速移动的样品，例如传送带，造纸机，或挤塑线等。
