摘要：

Two-dimensional spectrograms were obtained with the Vacuum Tower Telescope, Tenerife, in order to study small-scale structures and faculae on the Sun. Using the-speckle reconstruction method, we obtain high-resolution images and wavelength scans. Magnetic fields can be studied from Stokes V profiles, and velocity maps are gained by the Doppler shift of the center of gravity of Stokes I. Here some results about small-scale structures and their magnetic fields are shown.
