Abstract：
The paper describes the ultraviolet light beam profile and emittance measurement system for HLS (Hefei Light Source). The system is based on the optical measurement, composed by two functional blocks: optical imaging and image acquisition. The optical imaging system is to form the 1:1 image of the ultraviolet part of SR on the surface of the CCD. The image acquisition system receives NTSC signal from the CCD camera which acquires the image of the ultraviolet part of SR, the signal is processed by a LabVIEW program to obtain the beam information of beam profile size, emittance and coupling between vertical and horizontal directions. Some measured results are also given.
