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.
