Simplified interferometric method for the characterization of ultrashort optical pulses

我们提出了一种测量超快光脉冲电场的原型仪器。这项技术可应用于电信、生物成像、分子质谱和太赫兹辐射传感以及科学研究的许多分支。该仪器使用了一种新的手段，用于将脉冲的相位信息编码成一个信号，该信号可以用比脉冲的持续时间（通常在飞秒（10.15秒）制度）慢得多的响应时间的检测器进行测量，以及一种新的方法来处理数据以提取脉冲形状。与目前市场上的仪器相比，该仪器在提供的信息量、尺寸、灵敏度、操作参数范围、更新速度和抗噪音能力方面都将有更大的能力。

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)
