Research of Curved Artificial Compound Eyes Based on MEMS Technology
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.
