傅里叶变换光散射(FTLS)是一种结合光学显微镜、全息术和光散射来研究非均匀和动态介质的新的实验方法。在FTLS中，相干像场的光学相位和幅度被量化，并以数值方式传播到散射面。由于FTLS同时检测图像每个点的所有散射角(空间频率)，因此可以将其视为傅里叶变换红外光谱的空间等效，即在每个时刻检测所有的时间频率。
Fourier transform light scattering (FTLS) is a novel experimental approach that combines optical microscopy, holography, and light scattering for studying inhomogeneous and dynamic media. In FTLS the optical phase and amplitude of a coherent image field are quantified and propagated numerically to the scattering plane. Because it detects all the scattered angles (spatial frequencies) simultaneously in each point of the image, FTLS can be regarded as the spatial equivalent of Fourier transform infrared spectroscopy, where all the temporal frequencies are detected at each moment in time.
