Optical spectra and their temperature dependence have been investigated for a prototypical double-exchange ferromagnet La1-xSrxMnO3 (x=0.175). The optical conductivity spectrum above Tc is characterized by interband transitions between the exchange-split bands and gradually changes into intraband excitations with decrease of temperature, accompanied by conspicuous transfer of spectral weight over a wide energy region of 0-3 eV. The results indicate a large variation of the electronic structure with the spin polarization of the conduction carriers.
