One of the main challenges in integral imaging is to overcome the limited depth of field. Although it is widely assumed that such limitation is mainly imposed by diffraction due to lenslet imaging, we show that the most restricting factor is the pixelated structure of the sensor (CCD). In this context, we take profit from these sensor constraints and demonstrate that by proper binary amplitude modulation of the pickup microlenses, the depth of field can be substantially improved with no deterioration of lateral resolution.
