Abstract

As a snapshot 3D imaging technology, light field imaging is able to obtain the 3D information of objects in a single exposure and widely used in numerous fields. The paper analyzed the 3D imaging principles of defocused light field camera and elaborated the relationships between its performance indexes and structural parameters, then a performance index system of defocused light field camera was established. An image-telecentric optical system of defocused light field camera with wavelength range of 0.4-0.9μm, field-of-view of 24.5°, F-number of 5 was designed detailly. Aimed at the lack of a unified image quality evaluation method for defocused light field camera, it was proposed to add pupil aberration as an additional evaluation index on the basis of classical image quality evaluation. The result indicates that the designed defocused light field camera achieved excellent image quality and all indexes met the requirements.
