Therefore, it is imperative to develop a curved focal plane for visible thru near-infrared wavelength and to integrate it with simple optics. This proposal is aimed to demonstrate a compact camera module that consists of an optically curved image sensor and one single solid lens. The technology is based on spatially varied microlenses on planar image sensors. The microlens fabrication process is based on existing micromachining techniques from our lab so that it can be integrated into existing visible to near-infrared image sensors (more than 8 mega pixels). All these components are proven to be reliable in vigorous environment. There are three distinctive features of the proposed display: (1) The microlenses are made by lightweight polymers. The shape and focusing power of each microlens can be made different based on its position from the center of an image sensor. (2) A precision embossing process can be applied to create a non-planar substrate for microlenses. This feature can dramatically improve field curvature performance for a camera system. (3) Only one single solid lens is needed in front of the optically curved image sensor to reduce camera thickness and weight. In future, we can keep working on bio-inspired optics based on this project. In summary, more than 50% of camera modules are fabricated by Taiwan, but these products have limited profit due to high cost image sensors. It is hoped that fundamental technologies, such as optical system designs, bio-inspired optics and micro optics, could be established through this project. Eventually, knowledge learned through this project can be transferred into optical industry in Taiwan for improving competitive capability in the world.仿生物設計微透鏡bio-inspired opticsmicrolens
