Abstract
A terahertz imaging system based on a quantum-cascade laser (QCL), a fast scanning mirror, and a sensitiveGe:Ga detector is demonstrated. Transmission images are obtained by scanning the beam of the QCL across an object. Images with a diameter of approximately 40 mm and a signal-to-noise ratio of up to 28 dB were obtained within 1.1 s. The system was also used to obtain three-dimensional images of objects in an ellipsoidal volume with axes of approximately 40 mm by computed tomography within 87 s.
