Certain binary codes developed for spread-spectrum communication applications can be used to construct families of pseudorandom diffuser masks suitable for multiplex holography. Binary codes are used so that fabrication of the diffuser masks can be relatively straightforward. A simple technique is described for chirp-modulating the binary diffuser masks to achieve the advantage of polyphase masks, i.e., improved correlation properties, without having to construct them. Numerical comparisons of the correlation properties of optimal binary codes with and without chirp-modulation are presented.
为扩频通信应用开发的某些二进制编码可用于构建适用于多路复用全息术的伪随机漫射器掩模族。使用二进制编码以便漫射器掩模的制造相对简单。描述了一种对二进制漫射器掩模进行线性调频调制的简单技术,以实现多相位掩模的优点,即改善相关性,而无需构建它们。给出了有和没有线性调频调制的最优二进制编码相关性的数值比较。
