摘要:

复眼透镜是光场成像系统中的关键光学元件。提出一种针对复眼透镜的新型设计加工方法:该设计方法可根据不同的相机参数,优化复眼透镜的设计参数,提高成像质量;该加工方法主要包含超精密车削加工和模压注塑两道工艺,并对车削加工工艺进行了改良。在光场相机的基础上,对光场成像中合成孔径以及数字重聚焦等关键问题进行了深入探讨。试验结果表明,设计加工的复眼透镜阵列具有较高的精度和较好的一致性,可有效实现光场成像的核心功能。

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
