多焦繞射透鏡陣列應用在積體成像

Abstract

在積體成像的模擬中，主要包含兩大主軸，一個是三維資訊的接收，另一個是三維資訊的重建。此系統使用兩種光學軟體來進行模擬。利用code V的光學模擬來控制系統的光學特性；再來利用LightTools的光學追跡及照明功能，來模擬系統的影像成像特性。在整個模擬系統中，除了所需要的感光元件之外，微陣列透鏡的設置決定了整個系統大部份的參數控制。在本論文中，我們使用相位型菲涅耳波帶片做為積體成像中的微透鏡陣列；我們討論了菲涅耳波帶片對於色像差的影響及其模擬結果，同時我們也發展了重建影像計算方法及其應用。

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.
