光学相空时频层析成像

Optical Phase-Space-Time-Frequency Tomography

Paul Rojas, Rachel Blaser, Yong Meng Sua, Kim Fook Lee

摘要:

提出了一种新的构造光波场光学相位-空间-时间-频率层析成像(OPSTFT)的方法。这种层析成像可以通过使用一种新的四窗口光学成像系统的基础上,两个本振场平衡外差检测。OPSTFT是两个独立傅立叶变换对的维格纳分布函数,即,相空间和时间频率。从理论和实验上看,它可以提供空间光场的位置、动量、时间和频率等信息,其精度超过了不确定原理。我们模拟OPSTFT的光场遮蔽的电线和单线吸收过滤器。我们相信,四窗口系统可以提供量子图像处理和生物光子学的波场的空间和时间特性。

英文摘要:

We present a new approach for constructing optical phase-space-time-frequency tomography (OPSTFT) of an optical wave field. This tomography can be measured by using a novel four-window optical imaging system based on two local oscillator fields balanced heterodyne detection. The OPSTFT is a Wigner distribution function of two independent Fourier Transform pairs, i.e., phase-space and time-frequency. From its theoretical and experimental aspects, it can provide information of position, momentum, time and frequency of a spatial light field with precision beyond the uncertainty principle. We simulate the OPSTFT for a light field obscured by a wire and a single-line absorption filter. We believe that the four-window system can provide spatial and temporal properties of a wave field for quantum image processing and biophotonics.
