Plenoptic camera records the 4D light field data by storing the spatial information and angular information. Meanwhile, it introduces the trade-off between spatial resolution and angular resolution. We proposed a new camera design which has been modulated in Fourier domain. High resolution 4D light field could be reconstructed from the coded image by sparse reconstruction. A simulation is carried out to evaluate the performance of the camera design. The reconstructed light field has a better performance than the conventional plenoptic camera.
