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-quality reconstructed images with resolutions of up to 320 × 320 pixels. It can be extended to develop advanced imaging systems in the near-ultraviolet to terahertz region.
