The ciliary beating frequency in tissue culture from frog palate and lung was examined optically. Consecutive segments of the analog signal were then fast-Fourier transformed (FFT). The optical signals were measured as a function of the number of cilia by varying the examined area from 1.2 to 122 micron 2. The frequency of the maximum power of the spectra was independent of the measured area, while the line shape of the spectra and distribution of the main frequencies were strongly dependent on the dimensions of the area examined. The possibility that the width of the measured spectral peak reflects both the distribution of the beating frequencies and the distribution of the phases within the examined area is discussed.
对青蛙腭部和肺部组织培养物中的纤毛摆动频率进行了光学检测。然后对模拟信号的连续片段进行快速傅里叶变换（FFT）。通过将检测区域从1.2平方微米变化到122平方微米，将光学信号作为纤毛数量的函数进行测量。光谱最大功率的频率与测量区域无关，而光谱的线形和主要频率的分布强烈依赖于所检测区域的尺寸。讨论了测量光谱峰宽度既反映摆动频率分布又反映检测区域内相位分布的可能性。
