以即時電腦全像術實現人機互動之研究

Abstract

本篇論文為電腦全像片即時人機互動之實踐。首先我們修正疊代傅立葉演算法，演算法中加入相位修正及微調矩陣，改良相位式電腦全像片，使得重建影像對比度增加且強度分布更均勻。之後我們整合繪圖軟體以及感測器，並設計動作辨識，架設一人機互動環境。靠著傅立葉轉換公式的應用，讓電腦全像片可以直接在頻率空間計算，加速運算速度，達到即時輸出電腦全像片的效果。最後我們以空間光調制器顯示電腦全像片，並架設遠場繞射光學系統，完成即時互動系統。

The thesis is an implementation of real-time interactive CGH. We improvedcalculation speed to realize real-time rendering, and modified IFTA to enhancequality of kinoform CGH. Furthermore, combining with input/output instruments,we construct an interactive environment. Making use of the property of Fourier Transform, we were able to manipulate CGH in frequency domain, therefore we significantly improved the speed of calculation to achieve real-time application. By modifying a long-existing IFTA, noise in CGH is also reduced. Along with SLM and far-field diffraction optical system as output and infra-red motion sensor as input, the interactive environment was established.
