DESCRIPTION:Speakers: Michiel van Noort (MPS)\nTo infer the physical condi
 tions in the solar atmosphere\, it is necessary to record not only the spa
 tial distribution of the emerging radiation\, but also its spectral and po
 larimetric properties. Traditionally\, solar instrumentation has accomplis
 hed this by recording slices through the spatio-spectral domain\, and scan
 ning in the missing dimension. A Microlensed Hyperspectral Imager (MiHI) i
 s an instrument that is able to observe a spatio-spectral cube instantaneo
 usly\, thus eliminating the need to scan. This increases the photon effici
 ency of the observations\, and with the aid of state of the art cameras al
 lows for the acquisition of very high cadence data. Combined with image re
 storation\, high resolution spectra with a spatial resolution close to the
  diffraction limit of the telescope can be obtained at a cadence of less t
 han one second\, in all four Stokes parameters. The talk covers the basic 
 principle of operation\, data extraction and restoration\, and some exampl
 es of data recorded at the Swedish Solar Telescope.\n\nhttps://meetings.ai
