时空外差检测

Spatiotemporal heterodyne detection

Michael Atlan, Michel Gross

摘要:

我们描述了一个计划,其中的相机变成一个有效的可调谐频率滤波器的几个赫兹的带宽在离轴,外差光学混合配置,使执行并行,高分辨率的相干光谱成像。这种方法通过信号的空间和时间调制的组合来抑制噪声贡献而成为可能。本文解释了在布朗运动中悬浮粒子动态散射光的实验数据。

英文摘要:

We describe a scheme into which a camera is turned into an efficient tunable frequency filter of a few Hertz bandwidth in an off-axis, heterodyne optical mixing configuration, enabling to perform parallel, high-resolution coherent spectral imaging. This approach is made possible through the combination of a spatial and temporal modulation of the signal to reject noise contributions. Experimental data obtained with dynamically scattered light by a suspension of particles in brownian motion is interpreted.
