从全息成像角度出发,介绍了基于声光调制器的数字光栅的计算,提出了用小波变换的方法计算光栅的基本条纹,给出了条纹函数,实现了物理上可用的条纹模式,实验证明,该算法应用在数码光栅的计算上具有明显的优势和较强的鲁棒性。

This paper introduces algorithm of computing digital grating based on acousto-optic modulator for 3D holographic imaging. A new method of computing basis fringe by wavelet transform is proposed. Basis fringe function is computed and basis fringe model in physics is realized. Experimental results show that arithmetic is obvious advantage and robustness.
