The optical system enables the reduction of track length of the imaging device to achieve miniaturization. With the aid of optical engineering software ZEMAX, the multi-channel structure is simulated by a curved microlens array (MLA), and we used a Hypergon lens as the main lens to simulate the human eye, which can achieve the purpose of the wide field of view (FOV). With this architecture, each microlens of a MLA transmits a segment of the overall FOV. The partial images that are separately recorded in different channels are stitched together to form the final image of the whole FOV by software processing. This design is 2.70 mm thick, with 59 channels and 102˚× 90˚ FOV is optimized using ZEMAX ray tracing software on a 5.63 mm × 3.69 mm image plane. Given recent progress in the fabrication of microlenses, this image system has potentials to be commercialized. Due to the microlenses are realized by state-of-the-art micro-optical fabrication techniques on a wafer level that are suitable for application in mobile phone camera in the future. Finally, we will discuss the simulation results of this system and compare with a mobile phone patent.誌謝 i 中文摘要 ii ABSTRACT iii CONTENTS iv LIST OF FIGURES vi LIST OF TABLES xi Chapter 1 Introduction 1 1.1 Single aperture eye 2 1.2 Compound eye 2 1.3 Wide angle lens 3 1.3.1 Hypergon lens 4 1.3.2 Topogon lens 5 1.3.3 Metrogon lens 5 1.4 Wide angle lens camera 6 1.5 Microlens array (MLA) 7 1.5.1 Circular MLA 7 1.5.2 Other shapes MLA 9 1.5.3 Microlenses on a curved surface 12 Chapter 2 Aberration theory 17 2.1 Wave aberration 17 2.2 Seidel aberrations 20 2.2.1 Spherical aberration 20 2.2.2 Coma 21 2.2.3 Astigmatism 21 2.2.4 Field curvature 23 2.2.5 Distortion 23 2.3 Chromatic aberration 24 2.4 Ghost image 26 2.5 Overlap 27 Chapter 3 Design of a multi-channel imaging system 28 3.1 Literature review 28 3.1.1 Working principle 28 3.2 Design and optimizations 30 3.2.1 Hypergon lens 32 3.2.2 Microlens array design 34 3.2.3 The field apertures on an IR-filter 41 3.2.4 Image processing 45 Chapter 4 Image process 47 4.1 Flat field correction (FFC) 47 4.1.1 Description 47 4.1.2 Example images 50 Chapter 5 Results and discussions 52 5.1 System layout 52 5.2 Discussions 55 Chapter 6 Conclusion 63 REFERENCE 657375440 bytesapplication/pdf論文使用權限：不同意授權微透鏡人眼複眼手機鏡頭廣視角thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/261896/1/ntu-102-R00941053-1.pdf
