We propose a new technique for three-dimensional (3-D) imaging in arbitrary spectral intervals. It is based on a simultaneous diffraction of two divergent stereoscopic light beams on a single acoustic wave propagating in a uniaxial birefringent crystal. We discuss in detail this configuration of acousto-optic (AO) interaction, derive basic relations, and experimentally demonstrate the applicability of the proposed approach to 3-D spectral imaging. A stereo-imager of this type may be produced as an ultra-compact embeddable optical element, which is promising for many imaging applications.
我们提出了一种用于在任意光谱区间进行三维（3-D）成像的新技术。它基于两个发散立体光束在单轴双折射晶体中传播的单个声波上的同时衍射。我们详细讨论了这种声光（AO）相互作用的配置，推导了基本关系，并通过实验证明了所提出方法在三维光谱成像中的适用性。这种类型的立体成像仪可以制作为超紧凑的可嵌入式光学元件，这对于许多成像应用来说很有前景。
