Abstract
We review two techniques of indirect imaging of accretion discs in cataclysmic variable stars. The light curves of eclipsing systems depend on the distribution of surface brightness over the disc and the eclipse mapping method uses this information to find the continuum surface brightness image of the disc. The shapes of the emission lines from the disc are a function of both orbital phase and velocity. Doppler tomography combines the profiles of an emission line at many orbital phases to image the disc in the light of the line. The two methods are being used to solve problems concerning the physical conditions and the effect of the gas stream upon the disc.
