摘要：

We report a simple single-pixel imaging system with a low mean squared error in the entire terahertz frequency region (3-13 THz) that employs a thin metallic ring with a series of directly perforated random masks and a subpixel mask digitization technique. This imaging system produces high pixel resolution reconstructed images, up to 1200 x 1200 pixels, and imaging area of 32 x 32 mm(2). It can be extended to develop advanced imaging systems in the near-ultraviolet to terahertz region. (C) 2020 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
