Abstract: In order to strengthen the comprehensive quality of students on the photoelectric knowledge fusion, we take the major characteristics of Photonic and Electronic Engineering into consideration and propose to do the science teaching by micro-projects based on synthetically optical experiments. Students can take any technical solution to achieve the design objectives of the project while teachers take charge of the project selection and make sure that students could complete the design with high quality. Through this study and the training of such projects of designed experiments, students can enhance their practical ability and creativity.
