We discuss experimental techniques for measurement of the density of beam particles in both the transverse and longitudinal phase space. The second moments of a two-dimensional density in conjugate coordinates are combined to form the emittance, which remains invariant under idealized beam transport. Four different methods of emittance measurement are presented, as will be implemented at the Brookhaven Accelerator Test Facility.
