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.

目的：该程序的目的是显着推进同时在空间和时间上复杂，超快变化的光的测量技术。知识分子的优点：智力优点是开发了两个强大的单发装置来衡量这种光。 它还将涉及使用这些设备来测量重要的，目前无法估量的光脉冲，从而大大提高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最复杂的光脉冲。 另一个将首次测量单个任意光超快脉冲的完整时空强度和相位，特别是“超快灯塔”，也是“轻弹”。 更广泛的影响：更广泛的影响源于以下事实：有史以来最伟大的科学发现直接来自改进的测量光的方法。 不幸的是，大多数光线目前都是不可估量的，因为它涉及空间的同时复杂变化和时间上的超快变化。 结果，这些新设备在这个领域中显着扩展和改变人类的能力，应该在广泛的领域中找到应用，远远超出了该项目的应用程序。 例如，从组织中散布的光在空间上太复杂，并且时间过快，无法使用当前可用的方法进行测量，但是，如果可以测量，则最终可以使用该项目中开发的技术来最终用于强大的新医疗诊断。
