Abstract
A simple light field imaging system is proposed, which could improve the resolution of light field imaging and enhance the signal-to-noise ratio of the result image. In the experiment, the light field imaging system consists of a single CCD with a microlens array and a semi-transparent mirror. The Fourier slice theorem has been used to transform the four-dimensional (4D) light field information into an infinite number of two-dimensional (2D) slices. With the use of the semi-transparent mirror, the high spatial resolution image can be reconstructed on the terminal sensor. The proposed method can not only reduce the aliasing defocus degree in the imaging process but also improve the slice image resolution to meet the requirement of image definition.
