Single-shot Complete Spatiotemporal Measurement of Complex Light

目的：该计划的目的是显著推进测量同时空间和时间复杂的超快变化光的技术。智力上的优点：智力上的优点是开发了两个强大的单发装置来测量这种光。它还将涉及使用这些设备来测量重要的，目前无法测量的光脉冲，显着推进科学和技术的重要领域。一种设备将测量任意光脉冲的完整时间强度和相位，并用于测量有史以来故意产生的最复杂的光脉冲。另一个将首次测量单个任意超快光脉冲的完整时空强度和相位，具体来说，是一个“超快灯塔”和一个“光子弹”。更广泛的影响：有史以来绝大多数最伟大的科学发现都直接源于改进了的测量光的方法，这一事实带来了更广泛的影响。不幸的是，目前大多数光都是无法测量的，因为它同时涉及空间的复杂变化和时间的超快变化。因此，这些大大扩展和改变人类的新设备？美国在这一领域的能力，应该在更广泛的领域得到应用，远远超出这个项目。例如，从组织中散射的光在空间上太复杂，在时间上也太快，无法用现有的方法测量，但如果可以测量，原则上最终可以用于强大的新医学诊断，使用像这个项目中正在开发的技术。

Objective: The objective of this program is to significantly advance the technology of the measurement of simultaneously spatially and temporally complex, ultrafast-varying light. Intellectual merit: The intellectual merit is the development of two powerful single-shot devices to measure such light. It will also involve the use of these devices to measure important, currently immeasurable light pulses, significantly advancing important fields in science and technology. One device will measure the complete temporal intensity and phase of an arbitrary light pulse and be used to measure the most complex light pulses ever deliberately generated. Another will, for the first time, measure the complete spatio-temporal intensity and phase of a single arbitrary light ultrafast pulse, specifically, an "ultrafast lighthouse" and also a "light bullet." Broader impacts: The broader impacts follow from the fact that the vast majority of the greatest scientific discoveries of all time have resulted directly from improved methods for measuring light. Unfortunately, most light is currently immeasurable because it involves simultaneous complex variations in space and ultrafast variations in time. As a result, these new devices, which significantly extend and transform humankind?s capability in this realm, should find application in a wide range of fields, far beyond those in this project. For example, light scattered from tissue is too complex in space and too fast in time to measure using currently available methods but, if measurable, could in principle be used eventually for powerful new medical diagnostics using techniques like those being developed in this project.
