This paper introduces an artificial compound eyes imaging system with planar structure based on MEMS fabrication technology. Firstly, we used the photo-resist reflow method to fabricate a 9×9 microlens array on a planar glass substrate, as the lenses of the compound eyes. Its transverse size is 0.9 × 0.9 cm2 and thickness is about 0.7 mm. Then we built an imaging system where object images are captured by the micro-lens array using a CMOS camera. In the experiment, the imaging system is used to view a character ¿A¿. It is found that each microlens can image the character ¿A¿ effectively. As a result, a 9 × 9 multiple-image is captured in the CMOS camera. Finally, the object image is reconstructed from the multiple-image by digital process algorithm. The experimental results indicate that our system can effectively imitate the imaging mechanism of the compound eyes.
