Abstract
A new optical design inclusive of zoom optics and optical engine system is proposed in this paper. Traditionally, there is trade-off between F-number of projection optics and contrast, which seems that super high-contrast image from commercial projector was simply a dream. Some ideas of adaptive optics were announced before for the improvement of high contrast. However, few reach success or cost will be high. Traditionally, there is nothing to do with optics of projector and optical engine of projector if lens meets the specification. In this paper, a new optical design for optics and optical engine is studied with liquid optics arrays. Thanks to advanced optical design and LED light luminance, simulation results show that 50% improvement for image contrast could be made without sacrifice of volumetric size.
