摘要
太赫兹成像技术具有透视性、安全性以及光谱分辨能力等独特优点,有着广泛的应用前景。由于太赫兹面阵探测器的技术成熟度低、价格昂贵,太赫兹成像技术在较长时间内以单点扫描方案为主,存在系统复杂、成像耗时长等问题。近年来,基于计算成像算法的太赫兹单像素成像技术发展迅速,成为了获取太赫兹图像的重要途径之一。文章综述了太赫兹单像素计算成像技术的基本原理、技术实现手段和应用前景,总结了现存的一些关键问题,并展望了一些今后可能的发展方向。
Terahertz imaging technology has the advantages of perspective, safety and high spectral resolution,and has a broad applications prospect. Since terahertz detector arrays have low technological maturity and are of high cost, terahertz imaging techniques based on single-point scanning have been prevailing for many years, and have problems such as complex systems and long imaging time. Recently, computational imaging techniques have emerged as exciting approaches for achieving efficient terahertz single-pixel imaging. The basic principles,the experimental realizations, and application prospects of terahertz single-pixel computational imaging techniques were described. Some key challenges and potential solutions were discussed.
