| 摘 要： | 为解决主流太赫兹成像技术在成像速度、分辨力、清晰度以及制造成本等方面存在相互制约的问题，提出一种基于光控型空间调制器的太赫兹波快速成像技术。这一技术利用新型硅基太赫兹调制材料与数字微镜阵列器件(DMD)的集成，实现了基于单像素太赫兹探测器的快速成像，进一步分析了太赫兹波束分布特性和高斯背景对成像效果的影响，并提出了有效的优化方法。实验结果证实这种新型技术能够显著提高成像分辨力和清晰度。

| Abstract: | The mainstream terahertz imaging technology has mutual constraints in imaging speed, resolution, sharpness and manufacturing cost, etc. A fast terahertz wave imaging technology based on a light-controlled spatial modulator is proposed. This technology realizes the single-pixel terahertz detector by integrating the new silicon-based terahertz modulation material with the commercial Digital Light Processing(DLP) device. The influence of terahertz beam distribution characteristics and Gaussian background on imaging results is further analyzed. An effective optimization method is proposed. The rapid imaging results confirm that this new technology can significantly improve the imaging resolution and clarity. |
