该提案描述了开发能够扩展或压缩超快光学波形的时间尺度同时保持包络轮廓的完整性的时间成像系统的基本研究活动。 目标或建议是开发时间成像系统，能够解决飞秒功能的光学波形。 时间透镜将被制造为电光相位调制器谐振器将被设计用于调制器，具有非常高的电光系数的新晶体将被采用，并且非常高的频率（毫米波）源将被用于驱动谐振调制器。 新的国家的最先进的三维电磁场建模程序将被用来模拟复杂的介质加载谐振器的字段，通过字段的路径积分将被用来建立预期的峰值相位偏差。 许多应用可能会受到实际的时间成像系统的发展的巨大影响：通信，激光选择性光化学，和调查的光学波形超过目前可用的检测系统的能力。

This proposal describes basic research activities to develop temporal imaging systems capable of expanding of compressing the time scales of ultrafast optical waveforms while maintaining the integrity of the envelope profiles. The objective or the proposal is to develop temporal imaging systems capable of resolving femtosecond features in optical waveforms. Time lenses will be fabricated as electro-optic phase modulators resonators will be designed for the modulators, new crystals with very high electro-optic coefficients will be employed and very high frequency (mm wave) sources will be used to drive the resonant modulators. New state-of-the-art three dimensional electromagnetic field modeling programs will be used to model the field for the complicated dielectric-loaded resonators; path-integrals through the fields will be used to establish the peak phase deviations to be expected. Many applications could be greatly impacted by the development of practical temporal imaging systems: communications, laser selective photochemistry, and investigation of optical waveforms which ex ceed the capacity of currently available detection systems.
