Integral imaging using multifocal diffractive lens arrays

An optical system of picked-up and reconstruction for the three-dimensional information was designed. This system simulated by using code V optical design software and LightTools illumination design software, including lenslet array, receiver, and camera, has been calculated. The test images of the observed object can be obtained when light is penetrated through lenslet array. Then the image of the observed object can be reconstructed by using the computational integral-imaging reconstruction (CIIR) method. Thus, a commercial light field camera uses microlens array for integral imaging system is applicable. Lastly, we apply the phase Fresnel lens array to replace the microlens array, and diffractive lens array simulation concepts are demonstrated. The parameters of characteristic in the integral system applications are analyzed.
