摘要
随着太赫兹成像技术的发展,人们对太赫兹成像系统的成像性能如分辨率、成像速率、成像维度等均提出了越来越高的要求。为了消除衍射对太赫兹成像的影响,提高太赫兹成像系统所能达到的性能指标,许多学者已针对太赫兹数字全息技术进行了研究。首先对太赫兹数字全息的基本原理进行了概述,阐述并分析了目前国内外有关太赫兹数字全息成像的研究进展,这些研究显示太赫兹数字全息技术在提高成像分辨率、扩展成像维度等方面具有很大的发展潜力,且具备实时成像的能力,具有十分广阔的应用及发展前景。
With the development of THz imaging technique, there have been great demands for the improvement of THz imaging performances such as imaging resolution, imaging speed, image dimension, etc. To eliminate the influence of diffraction on imaging results and to improve the performance of THz imaging system, a lot of researchers have turned their attentions to THz digital holography. Firstly, some fundamental theories for THz digital holography are briefly introduced. Then a comprehensive description on the advances in the domestic and international research of THz digital holography is povided. These investigations exhibit that THz digital holography has great potentials to improve the imaging resolution and extend image dimension, etc. Moreover, THz digital holography has the capability of real-time imaging. Those characterizations make THz digital holography a promising technique which has an exciting application and develooment orosDect.
