  An interferometer system and an imaging system using visible synchrotron
radiation (SR) have been installed in HLS II storage ring. Simulations of these
two systems are given using Synchrotron Radiation Workshop(SRW) code. With
these two systems, the beam energy spread and the beam emittance can be
measured. A detailed description of these two systems and the measurement
method is given in this paper. The measurement results of beam size, emittance
and energy spread are given at the end.
