摘要

We firstly propose the technique to realize far-filed image by integrating the microlenses array with LCD. This technique is expected to resolve eye-gazing problem in common teleconferencing system without affecting the display performance of LCD. The characteristics of far-field diffraction image and geometric image formed by single microlens are simulated and analyzed. The simulation shows that the quality of image is seriously reduced by geometric aberration and diffraction of the small aperture diameter for aspherical and spherical surface profile refractive microlens. The main problem of image acquisition with high resolution is that the signal obtained by cell detector is contributed not only by the sampling point in the axis of the corresponding cell microlens but also sampling points nearby. In simulation,rnMicrolenses of 300μm diameter same with pixel size of LCD were used in orthogonal array at 1mm pitch, which is alsornthe sampling interval in object space. These microlenses array with unit number 213×246 are placed up to 600mm away from object surface. Monte Carlo optimization algorithm is adopted to give accurate inversion results. The typical results are presented with our main conclusions.
