The equivalent ray geometry of two horizontally aligned detectors at the focal plane of the main antenna in a millimeter wave imaging system is analyzed to reveal the reason why the images from the detectors are fused as an image with a depth sense. Scanning the main antenna in both horizontal and vertical directions makes each detector perform as a camera, and the two detectors can work like a stereo camera in the millimeter wave range. However, the stereo camera geometry is different from that of the stereo camera used in the visual spectral range because the detectors' viewing directions are diverging to each other and they are a certain distance apart. The depth sense is mainly induced by the distance between detectors. The images obtained from the detectors in the millimeter imaging system are perceived with a good depth sense. The disparities responsible for the depth sense are identified in the images.
分析毫米波成像系统中主天线焦平面上两个水平对齐探测器的等效射线几何结构，以揭示探测器的图像为何会融合成具有深度感的图像。在水平和垂直方向上扫描主天线，使每个探测器都能像相机一样工作，并且这两个探测器在毫米波范围内可以像立体相机一样工作。然而，立体相机几何结构与视觉光谱范围内使用的立体相机不同，因为探测器的观察方向相互发散且它们之间有一定距离。深度感主要由探测器之间的距离引起。在毫米波成像系统中从探测器获得的图像具有良好的深度感。在图像中识别出产生深度感的视差。
