In order to realize the sharing of high quality course resources and promote the deep integration of ‘Internet+’ higher education and talent training, a new on-line to off-line specialized courses teaching mode was explored in Chinese colleges and universities, which emphasized different teaching places, being organized asynchronously and localized. The latest progress of the Chinese National Optical Education Small Private On-line Course (CNOESPOC) system set up by Zhejiang University and other colleges and universities having disciplines in the field of optics and photonics under the guidance of the Chinese National Steering Committee of Optics and Photonics (CNSCOP) was introduced in this paper. The On-line to Off-line (O2O) optical education teaching resource sharing practice offers a new good example for higher education in China under the background of Internet +.
Curriculum design and simulation courses are bridges to connect specialty theories, engineering practice and experimental skills. In order to help students to have the computer aided optical system design ability adapting to developments of the times, a professional optical software--Advanced System of Analysis Program (ASAP) was used in the research teaching of curriculum design and simulation courses. The ASAP tutorials conducting, exercises both complementing and supplementing the lectures, hands-on practice in class, autonomous learning and independent design after class were bridged organically, to guide students "learning while doing, learning by doing", paying more attention to the process instead of the results. Several years of teaching practice of curriculum design and simulation courses shows that, project-based learning meets society needs of training personnel with knowledge, ability and quality. Students have obtained not only skills of using professional software, but also skills of finding and proposing questions in engineering practice, the scientific method of analyzing and solving questions with specialty knowledge, in addition, autonomous learning ability, teamwork spirit and innovation consciousness, still scientific attitude of facing failure and scientific spirit of admitting deficiency in the process of independent design and exploration.
The goal of National University Students’ Optical-Science-Technology Competition (NUSOSTC) is to provide a nation-wide platform for students from the colleges and universities, which have majors in the field of optics and photonics, to communicate and learning each other. Meanwhile, it works on pushing forward the popularity of optoelectronic knowledge, cultivating the students' teamwork and innovation ability, promoting higher education personnel training mode and practice teaching reform, and then improving the quality of talent training. The founding, organizational structure development and overall organizational arrangements of NUSOSTC were introduced in this paper. Besides, the competition logo, theme, title, final date, numbers of participating universities, undertaking universities and cities of the five NUSOSTCs held during 2008 to 2016 and the progress had been made were given in detail.
In the teaching of design courses, the process of students to complete the designs is considered more important than the final results, and usually there are no standard answers for these designs. Thus, the research on the process evaluation method in design courses is of great significance. Taking the assessments of two design courses in optical discipline as examples, the psychophysical experimental methods are introduced into the process evaluation of the design courses, i.e. the process evaluation given by each student to others in forms of classification, sorting or grading are adopted as one trial of a psychophysical experiment, which generate many experimental data of mutual evaluation. Based on these data, evaluation results are measured scientifically using the statistical method. Furthermore, through correlation analysis and regression analysis of these data, the relationship among various aspects of different process can be studied. It is easier for students to understand and accept their assessment results, and more helpful for teachers to analyze the influencing factors in their teaching process.
The optimized curriculum of College of Optical Science and Engineering is accomplished at Zhejiang University, based on new trends from both research and industry. The curriculum includes general courses, foundation courses such as mathematics and physics, major core courses, laboratory courses and several module courses. Module courses include optical system designing, optical telecommunication, imaging and vision, electronics and computer science, optoelectronic sensing and metrology, optical mechanics and materials, basics and extension. These curricula reflect the direction of latest researches and relates closely with optoelectronics. Therefore, students may combine flexibly compulsory courses with elective courses, and establish the personalized curriculum of “optoelectronics + X”, according to their individual strengths and preferences.
The employers in optical engineering fields hope to recruit students who are capable of applying optical principles to solve engineering problems and have strong laboratory skills. In Zhejiang University, a hierarchy curriculum for practical skill training has been constructed to satisfy this demand. This curriculum includes “Introductive practicum” for freshmen, “Opto-mechanical systems design”, “Engineering training”, “Electronic system design”, “Student research training program (SRTP)”, “National University Students’ Optical-Science-Technology Competition game”, and “Offcampus externship”. Without cutting optical theory credit hours, this hierarchy curriculum provides a step-by-step solution to enhance students’ practical skills. By following such a hierarchy curriculum, students can smoothly advance from a novice to a qualified professional expert in optics. They will be able to utilize optical engineering tools to design, build, analyze, improve, and test systems, and will be able to work effectively in teams to solve problems in engineering and design.
In this talk, we are going to present our new try to set up National Optical Education Small Private Online Course (SPOC) system, which relates about 15 universities who has optical engineering education around China. The SPOC system is guided by the National Teaching Steering Committee, and is designed to enhance the sharing the best teaching and training resources in the advanced university to the other universities all over the China.
A research is carried out on the characteristics of CMOS (Complementary Metal-Oxide Semiconductor) image sensors. A
CMOS image sensor is used to probe the fluorescence intensity of atoms or absorbed photons in order to measure the
shape and atomicity density of Rb (Rubidium) cold-atom-cloud. A series of RGB data of images is obtained and the
spectrum response curve of CMOS image sensor is deduced. After filtering out the noise of the pixel signals of CMOS
image sensor, the number of photons received by every pixel of the CMOS image sensor is obtained. Compared with
CCD camera, the CMOS image sensor has some advantages in measuring the properties of cold-atom-cloud,such as
quick response, large sensory area, low cost, and so on.
An instrument used to measure the normal specular reflectance of curved optical surface made with transparent material
is presented. Instead of the half mirror, i.e. the mirror with 50% reflectance that was commonly used in the previous
spectral reflectometers, a specially designed patterned mirror is introduced that can reduce the optical energy loss due to
half mirror as many as 50%. The signal-noise rations of the instrument are significantly improved especially in the UV
spectrum range. The interference reflection of back surface of the optical components can be effectively prevented by the
conjugated optical design. The diameter of measurement spot size in the test surface is about 60 micrometer and the
repeat accuracy of measurement results is better than ±0.01% over wavelength 410-700nm.
