Simplified interferometric method for the characterization of ultrashort optical pulses

我们计划研制一台用于测量超快光脉冲电场的样机。这项技术在电信、生物成像、分子质谱仪和太赫兹辐射传感以及科学研究的许多分支中都有应用。该仪器使用一种新的方法将关于脉冲的相位信息编码成可以用响应时间比所寻求的脉冲的持续时间慢得多的检测器测量的信号(通常在飞秒(10.15秒)范围内)，以及使用一种处理数据以提取脉冲形状的新方法。该仪器在提供的信息量、大小、灵敏度、操作参数范围、更新速度和对噪声的稳健性方面将比目前市场上的仪器具有更强的能力。项目持续时间(月)

We propose to develop a prototype instrument for measuring the electric field of ultrafast optical pulses. This technology has applications in telecommunications, biological imaging, molecular mass spectrometry and TeraHertz radiation sensing as well as in many branches of scientific research. The instrument uses both a novel means for coding phase information about the pulse into a signal that can be measured with detectors of much slower response time than the pulses whose duration is sought (typically in the femtosecond (10.15 sec) regime), and a new method for processing the data to extract the pulse shape. The instrument will have enhanced capabilities compared to those currently on the market in terms of the amount of information provided, size, sensitivity, operating parameter range, rapidity of update and robustness to noise.Duration of Project (months)
