Descripción
We present a summary of the concept design report of a new astronomical
instrument: SPARC4, Simultaneous Polarimeter and Rapid Camera in 4
bands. SPARC4 will provide photometry and polarimetry in four optical
broad bands (griz SDSS) simultaneously. This is achieved by the use of
dichroic beam splitters. The square eld of view is around 5.6 arcmin on
a side. SPARC4 time resolution is sub-second for photometry and somewhat
longer for polarimetry. This is provided by the use of fast EMCCDs. The
main motivation for building SPARC4 is to explore astrophysical objects
which exhibit fast temporal variability in ux and polarization. The
instrument will be installed at the 1.6-m telescope of the Observatorio
do Pico dos Dias (Brazil).
