Near-field terahertz imaging with a dynamic aperture
By introduction of an optical gating beam on a semiconductor wafer, near-field terahertz (THz) imaging with a dynamic aperture has been realized. The spatial resolution is determined by the focus size of the optical gating bean and the near-field diffraction effect. THz imaging with subwavelength spatial resolution (better than 50 {mu}m ) is demonstrated. (c) 2000 Optical Society of America.
