The orientation of talents cultivation for local colleges is to train engineering application-oriented talents, so the exploration and practice on teaching reform of theory curriculum was carried out. We restructured the knowledge units basing on numerical solution problems, and chose the software to build algorithm models for improving the analytical and designed ability. Relying on micro video lessons platform, the teacher-student interaction was expanded from class to outside. Also, we programmed new experimental homework, which was suited for process evaluation. The new teaching mode has achieved good effect, and the students' application ability was significantly improved.
Confocal endomicroscopy has been developed very quickly for its high resolution and high sensitivity. It could be used
for early diagnoses of disease, such as cancer. In existing confocal endomicroscopy, fiber bundle or single fiber was used
for transferring exciting laser and excited fluorescence signal. Neither of these technologies had high resolution nor high
imaging speed. In this paper, a fast confocal endomicroscopy(FCM) is presented. In the FCM, a multi-fiber array with 9
fibers is used for light signal transferring, including exciting laser and excited fluorescence. In the distal end of the
endomicroscopy, the fibers are arranged in two dimension and form a 3X3 area array. The fibers are not arrayed closely,
but with space. Under driving of a MEMS scanner, the fibers move and scan tissue in parallel. Each fiber takes charge of
1/9 of the whole diagnoses field. Then the whole field is scanned and image is acquired. In the other end, the fibers are
arranged in linear array. Exciting laser is coupled into the linear fiber array and transferred to the distal end of the area
fiber array. Fluorophore molecules in tissue are excited and emit fluorescence. The fluorescence is collected into the 3X3
area fiber array and transferred to the linear array end. An imaging objective lens couples the fluorescence from the fiber
end to a CCD, which converts the light intensity into electrical signal. Image of tissue is reconstructed from the electrical
signal. By parallel scanning, the imaging speed of confocal endomicroscope is improved by several times, which is
associated with the number of fibers in the array.
