Whole Life Cycle

The life cycle of the sugarcane smut fungus Sporisorium scitamineum is a multistep process. Haploid sporidia of compatible (MAT-1 versus MAT-2) mating types fuse to generate pathogenic dikaryotic hyphae to infect the host. Within the host tissues, diploid teliospores are formed and induce a characteristic sorus that looks like a black whip. The diploid teliospores germinate to form haploid sporidia by meiosis. In order to monitor fungal development throughout the whole life cycle, we expressed the green fluorescent protein (GFP) and red fluorescent protein (RFP) in S. scitamineum MAT-1 and MAT-2 sporidia, respectively. Observation by epifluorescence microscope showed that conjugation tube formation and sporidia fusion occurred at 4 to 8 h, and formation of dikaryotic filaments was detected at 12 h after mating. The resultant teliospores, with diffused GFP and RFP, underwent meiosis as demonstrated by septated hypha with single fluorescent signal. We demonstrated that GFP- and RFP-tagged strains can be used to study the life cycle development of the fungal pathogen S. scitamineum, including the sexual mating and meiosis events. This dual-color imaging system would be a valuable tool for investigation of biotic and abiotic factors that might affect the fungal life cycle development and pathogenesis.

The detection technique of small module gears has a very important research and application value. In this paper, a composite measuring method is presented based on combining traditional mechanical contact measurement with optical image non-contact measurement. First of all, this paper analyzes the basic principle of composite probe composed of optical fiber stylus and CCD imaging system. The tail-end of the stylus is shaped into a micro-sphere, where a small refection mirror is designed. When the laser is transmitted through the fiber, a round facula can be seen from the CCD camera. The micro-sphere is kept contact with the surface of the measured gear at the time of measuring and the error of the measured gear will be reflected by the offset of the facula center. Meanwhile, the sub-pixel extraction algorithm for the center of facula image is presented. Then the calibration principle and method of probe system is analyzed in detail. Finally, the data processing principle of the presented method is discussed for gear measurement.

Based on research of the traditional phase-shifting profilometry (PSP) method, a tilted measurement system is proposed. The proposed technology makes three constraints of the traditional phase-shifting profilometry measurement system less constrains. The exit pupil of the projecting system and the entrance pupil of the CCD imaging system are not horizontal and not placed at equal height. The optical axis in the CCD imaging system is not necessarily perpendicular with a specific tilting angle to the reference plane. The optical axises of the CCD imaging system and projecting system are not coplanar. The two axises do not intersect with each other. Compared to the traditional phase-shifting profilometry the proposed method offers a flexible way to calculate height distribution.

The Impact

This paper studies the fabrication of curved surface artificial compound eyes and application in the optical imaging system. At present, the planar artificial compound eyes imaging system has narrow field of view angle because of its flat array structure of compound eyes. The preparation process of some existed curved surface artificial compound eyes is very complex and is very difficult to guarantee their exact curvature of the substrate. This paper presents a new method to fabricate the curved artificial compound eyes precisely based on MEMS technology The base diameter of the compound eye lens surface is 8mm and the height is 3mm, which includes thousands of compound eyelet. The diameter of the eyelet is 170μm, and the height is18μm. We use this curved artificial compound eyes and CCD imaging sensor assembly,aside from the impact of edge effects,we get the multi-angle and multi-dimensional photography to one object in the center of the imaging area. Therefore, the curved artificial compound eyes optical imaging system has a strong advantage in the dynamic spatial orientation.
