With small size, light weight , integrated, large field of view and high sensitivity，artificial compound eyes have important applications in the detection of space debris , a full range of missiles guiding, unmanned aerial vehicles and robot vision and so. Whereas, the traditional microfabrication processes are difficult to meet the needs of manufacturing of high precision micro-optical elements with such great arch of highly complex three-dimensional configurations. This project proposes a femtosecond laser wet etch new method for the wide-view micro-optic components manufacturing. It will carry out the studying in transient mechanism of interaction between femtosecond laser and materials, modification mechanism of laser fine-tuning materials, chemical wet etching of material modified zone, micromachining process of artificial compound eyes，and gradually clarify the mechanism of activated, modified chemical bond in material absorbing the photon energy, precisely regulate the interaction between laser and material to achieve targeted modification.The aim of this study is to obtain new principles and methods of energy deposition controls of light-affected zone material during the laser zone-by-point scanning, chemical wet etching and polishing, to improve the efficiency, accuracy and quality of micro-optical components,and getting a breakthrough in manufacturing the high-arch, complex three-dimensional configuration micro-optics, exploring a new method of femtoscond laser micormachining of the high-performance compound eye.
