合成孔径法是一种有吸引力的太赫兹无损成像技术，对光束形式和瑞利聚焦长度没有严格的限制。然而，接收机阵列孔径的限制导致了重构图像的畸变和侧向分辨率的限制。本文介绍了一种非线性成像处理原理——相关合成法，该方法已在超声测量中得到应用。利用脉冲反射模式太赫兹时域光谱系统和脉冲压缩预处理，重建了金属圆柱体的图像。与合成孔径法的对比结果验证了相关合成法在提高横向分辨率和消除假像方面的有效性。
The synthetic aperture method is an attractive technique for terahertz nondestructive imaging without strict restraints on the beam form or the Rayleigh length of focus. However, the limitation of the aperture of the receiver array results in distortion and restricted lateral resolution of the reconstructed image. This paper introduces a nonlinear imaging processing principle, the correlating synthesis method, which has been applied in ultrasonic measurements. Using a pulse reflection mode terahertz time-domain spectrometry system and pulse compression preprocessing, we reconstructed images of metal cylinders. The results of comparisons with a synthetic aperture method verify the efficiency of the correlating synthesis method for improving the lateral resolution and eliminating fake images.
