资料〔1〕首先介绍了调制盘的一种令人感兴趣的应用。文中概略介绍了由傅里叶分量构成任意周期性波函数的方法。该文作者采用了一个外形固定的孔径和一个位于旋转调制盘上的可变孔径。每一对这样的孔径要能产生与每个被合成的信号谐波相当的传输函数。穿过任意固定孔径的全部光通量是作为调制盘的位置以及时间的函数而进行调制的。实际上,与所需信号的多个谐波相应, Data [1] first introduced an interesting application of the modulation disk. In this paper, we briefly introduce the method of constructing arbitrary periodic wave functions by Fourier components. The author uses a fixed aperture and a variable aperture on the rotary dial. Each pair of such apertures is capable of producing a transfer function that is comparable to the harmonics of each synthesized signal. The total luminous flux passing through any fixed aperture is modulated as a function of the position and time of the modulation disk. In fact, corresponding to the multiple harmonics of the desired signal,
