全像影像應用於影音互動裝置系統設計之研究

Abstract

隨著數位點矩陣全像片(Dot matrix hologram)技術之發明，透過控制光柵間距、角度、點尺寸之不同可以改變全像片顯示之色彩、觀看的角度、以及解析度，並透過電腦軟體或程式設計出不同視覺效果的全像影像。本研究主要目的是藉由自行設計之點矩陣全像片光影變化的頻率，經由攝影機即時判讀後，合成音訊，產生音樂節奏快慢之差異。使用者能在不同操作模式中，透過改變全像影像之光影變化效果，引起不同效果之音訊反應。研究為加強偵測之準確率與全像光影呈現效果，亦針對光源入射角度與繞射光線之色彩作進一步探討。本研究之影音互動裝置除能夠拓展全像片的加值應用領域外，未來並將能提供藝術表現、數位學習、遊戲設計及防偽辨識等領域之參考。With the invention of dot-matrix holographic techniques, the displayed colors, viewing angles and the resolutions can be controlled by adjusting the grating pitch, the grating orientation, and the spot size. The objective of this study is to develop an interactive system that can synthesize audio in accordance with the variations in brightness of the diffractive light from a hologram. In order to improve the accuracy of timing of the synthesized audio from the hologram, the fundamental concept of diffraction and signal processing are used. This real-time interactive system has great potential to creative art presentation, e-learning, game development and anti-counterfeiting applications.
