英文摘要：

Background： The optical system controlling of Shanghai Deep Ultraviolet Free-Electron Laser （SDUV-FEL） is based on EPICS system framework. It contains hardware and software to realize the functions like optical path control, beam quality measurement and so on. Purpose： Some improvements are needed so as to facilitate the operation and the safety of the maintenance and repair. All parts of this system should be integrated to the EPICS framework. Methods： We have made following improvements： integration of Basler CCD to EPICS, new OPI, controlling system of stepper motor through serial network. Results： All basic functions of the CCD and motor control are realized, meanwhile, all the optical systems are under the control of EPICS, which meet the need for FEL experiments. Conclusions： This work will make further enhance simplicity and integration of the optical system, which will become more reliable, easily operated and maintained.
