Abstract: In this paper we present the test spectropolarimetric observations of the spicules in the Hα and He I D3 multiplet for different high chromospheric altitudes from 5000 km to 7000 km using the innovative Polarization-Holographic Imaging Stokes Polarimeter (PHISP) mounted on the 53-cm coronagraph of the Abastumani Astrophysical Observatory (Georgia). The laboratory tests and first spectropolarimetric observations show that the resulting uncertainties are estimated to be of the order of 10^-3.
