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.

立体图像的声光可调光谱滤波

我们提出了一种新技术，用于在任意光谱间隔中进行三维（3-D）成像。它基于在单轴双折射晶体中传播的单个声波上两个发散的立体光束的同时衍射。我们将详细讨论声光（AO）相互作用的这种配置，得出基本关系，并通过实验证明所提出的方法在3-D光谱成像中的适用性。这种类型的立体成像器可以被制造为超紧凑的可嵌入光学元件，这对于许多成像应用是有前途的。
