Abstract

Abstract:

Compound eye lens is the key component in light field system. A novel design and manufacturing method is proposed. The parameters of compound eye lens are optimized based on different cameras so that the quality of the image is improved; the manufacturing process mainly includes modified ultra-precision turning and mould injection. Besides, the synthetic aperture and digital refocusing related to light field imaging are discussed. The results of experiments show that the high accuracy and repeatability of compound eye lens arrays are achieved by utilizing the proposed method and the core function of light field image is also achieved.

Key words: light filed imaging, ultra-precision machining, compound eye
