| Abstract: | It described horizontal scanning technologies of confocal technology in detail and introduced the structure and principle of confocal microscope based on digital micromirror device (DMD). Besides, the parallel detection system based on DMD was established, and the optical path design was optimized as well. It was found that in the normal optical system there was reflection on the inner surface of prism, which causes double images on CCD. Based on theoretical analysis and repeated experiments, spectral plates were taken the place of splitting prism and the refection on inner surface of prism was eliminated. A promoted optical system is achieved. |
