The optical instrument design is a major direction for the students of Measuring & Control Technology and Instrumentations Major, as a traditional major in Changchun university of science and technology (CUST, the original name is Changchun Institute of Optical and Fine Mechanic, CIOM), we maintain the special feature that the optics is combined with fine mechanics during teaching. So, the major direction is the interdisciplinary of optical engineer and instrument science and technology. Therefore, there are two main line be design about the courses, one is the optical courses include the Physical optics, Applied Optics, Photoelectric Detection Technology, Optical Measurement, Optical Design and CAD etc., and another main line is the fine mechanical courses such as Theory of Engineering Drawing, Machine and Mechanisms, Fundamentals of Interchangeability and Measurement Technology, Error Theory and Data Processing, Instrument Elements Designing, Photoelectric Instrument Design, etc.. Furthermore, the courses about electronics and information are offered according to the most general engineering majors. A lot of links consist in these courses, But some student can’t understand the undertake relations of them, and some teacher can’t clear the aim of the courses, even the same contents are taught twice in different course. For solving the above problems, This paper focuses on the sequence and the structural logic of the curriculum system.
Almost the cultivation goal of different major can be concluded in the general standards and distinguishing standards. Firstly, the general standards include the requirement such as, the basic knowledge, the ability of independent learning and lifelong learning, the cognition of team spirit and social responsibility. Secondly, the distinguishing standards are the requirement about the specialized knowledge, the specialized skill and the ability to finish the project. [1,2] The system diagram of cultivation goal and courses as Fig.1. The optical instrument design major being introduced in this paper combines the tradition of CIOM with the advantage in optical field, the main distinguishing standards as follows:
(1) Through systematical learning and training, multiform teaching and engineering practice with the program, Graduates can master the theories such as Photoelectric Instrument Design, Intelligent Instrument, Optical Design, Accuracy Analysis of Instrument, Instrument Manufacturing Technique, Optical Instrument Assembly and Adjustment, gain abilities of technology integration and precision instrument design.
(2) Graduates can design and solve the engineering problems in the field of precision instruments.
(3) Graduates can track the development of new technologies in the field of precision instruments, and to solve complex engineering problems in special environments.
The Proportion Relationship of the Courses
The quantity compare of all courses
As shown in Fig.2. There are 16 required basic general courses, furthermore, 3 to 6 quality-oriented education courses should be elected in order to achieve the credit requirement, so the total quantity of the general basic course is about 21, there are15 basic disciplinary courses, they are all the required courses, and the quantity of the specialized required courses.
The analysis of basic disciplinary courses and specialized course
The basic disciplinary courses and specialized course are the important reflections of realizing the cultivation goal. 22 courses include the disciplinary courses and specialized course are required for the student graduating. They can be classified mechanical courses, optics courses and electronic and information courses. The Fig.2 shows the courses’ quantity of different categories, and the Fig.3 shows the courses’ class hours of different categories. It is almost inevitable that some course belong to two even all three categories, so we list these courses in the Tab.1, the “#” in front of the course’s name mean that the course is belong to the optics and electronic and information at the same time, the “*”mean that the course belong to the optics and mechanical. From the quantity and class hours, we can find the optics and mechanical courses is the main component.

There are 9 Mechanical Courses, the Error Theory and Data Processing and Accuracy Analysis about Instrument are classified into this type because that they are the leading courses of instrument accuracy and error analysis. Among the 8 optics courses, Photoelectric Detection Technology belongs to the optics and electronic and information, the main content of “Photoelectric Instrument Design” and “Optical Instrument Assembly and Adjustment” are about the fine mechanic, the knowledge about optical instrument design is taught in the two courses, so they belong to the optics and mechanical. It can be concluded that the theory and knowledge of optics is the characteristic of the major.
THE SEQUENCE OF COURSES
About the sequence of courses, we consider the way backward from the target, which is start from the last specialized courses or practical training, the leading courses for them are researched, all the needed courses are arranged until the public basic course step by step.  The cultivation goals are considered mainly during the curriculum are designed. The courses’ sequence in all semesters is shown in Tab. 2, the table does not list the basic general courses which are set up in most colleges and universities in China, such as Ideological and Political Education, Foreign Language, P.E., and modern history of China.

THE ANALYSIS OVERLAPPING PROBLEM OF CURRICULUM
There are two main reasons about the overlapping problem of curriculum, the first reason is knowledge convergence, the overlapping content is the basic knowledge of the course, it is needed for the course’s systematic. For example the content of the instrument accuracy analysis in the course of Photoelectric Instrument Design, another similar example is the some knowledge in Theory of Machine and Mechanisms is introduction in Instrument Elements Designing. The second reason is interdisciplinary, some knowledge is described in different courses. The example is the knowledge about the optical source is taught in both courses which Applied Optics and Photoelectric Detection Technology. The main overlapping problem of curriculum as Fig.2.

THE COURSES’ GOAL AND THE LOGIC OF CURRICULUM
The fundamental order of the courses can be get base on the courses’ systemize. The main relation of the courses about the major of optical instrument design as Fig.4, It is the main line how the design capacity for photoelectric instrument is trained. It begin with the Engineering Drawing, then, the courses such as Engineering Mechanics, Theory of Machine and Mechanisms, Instrument Manufacturing Technique, Instrument Elements Designing, CAD about Parts of Instruments are set up in sequence, until Instrument Elements Designing is taught as a comprehensive course. During the main courses in the main line are taught, the electricity basic courses, the courses about sensor and detection technology, the courses about optics, the courses about accuracy theory are all be taught too. These courses are the basic knowledge for the students who are able to design the photoelectric instrument.
Base on the courses’ systemize, we can make it clear which course should belong to that the different overlapping content. So we can forms the syllabus, and make the courses’ education goal.
The main line and the order of the courses can be made clear through optimizing the curriculum system, these provide a basis of the course plan. Therefore, We conclude the overlapping problem of curriculum, and find it’s reason, So the course objectives and syllabus are optimized accordingly.
