  • Abstract
    A reflection imaging system based on the terahertz quantum-well photodetector is presented. Reflected terahertz imaging of a logo on a universal serial bus (USB) flash disk is demonstrated. A spatial resolution better than 0.4 mm is achieved. This experiment demonstrates that the quantum-well photodetector is potentially useful for reflection imaging applications.
