1960年代受限於實驗技術，有關於分子動力學之理解進展緩慢，直至運用交叉分子束技術後，問題始得解決。國立科學工藝博物館（以下簡稱科工館）典藏之交叉分子束儀器（HOPE），1967年由李遠哲院士於哈佛大學赫胥巴赫實驗室（The Laboratory of Herschbach）期間，親自繪圖設計並偕同研究團隊開發組裝，係為當時首部得以研究非金屬物質如何進行化學分子反應之實驗裝置，成為世界上第一台通用型交叉分子束儀器，李遠哲也因此榮獲1986年諾貝爾化學獎。HOPE現於科工館「科學桂冠廳」展出，僅以圖文面板以及影音介紹如何從哈佛大學到科工館、申請指定國寶等歷程。為能讓HOPE國寶不僅是象徵意義的存在，依據博物館非制式場域的特性，將開發為可讓觀眾自主學習的互動展示。在不觸及國寶本體的條件下，預定以「外加」的虛實融合互動展示方式呈現，巧妙運用HOPE的正面內部腔體為「實」，以透明顯示器為「虛」，透過透明投影技術以及辨識互動技術，將交叉分子束儀器介紹呈現於透明介面上，亦即將以直視型AR擴增實境技術建置為互動展示。李遠哲對於未知的問題，找答案的方法是自己設計製作儀器，去嘗試去思考，展現科學實作的精神；透過進行中的虛實融合互動展示方式，讓觀眾來體驗來操作，運用展示科技呈現實驗過程，應有利於科普推廣之進行。

In the 1960s, limited by experimental technology, the understanding of molecular dynamics progressed slowly. It was not until the use of crossed molecular beam technology that the problem was solved. The Crossed Molecular Beam Instrument (HOPE) in the collection of the National Museum of Science and Technology was designed by Yuen-Tseh Lee himself in 1967 while he was at the Laboratory of Herschbach at Harvard University and developed and assembled together with the research team, was the first experimental device at that time to study how non-metallic substances undergo chemical molecular reactions, and became the world's first universal cross-molecular beam instrument. For this, Yuen-Tseh Lee won the 1986 Nobel Prize in Chemistry. HOPE is now on display in the "Science Laureate Hall" of the Science and Technology Museum. It only uses graphic panels and videos to introduce the process of getting from Harvard University to the Science and Technology Museum, applying for designated national treasures, etc. In order to make the HOPE national treasure not only a symbolic existence, but also based on the characteristics of the museum's non-standard field, an interactive display will be developed that allows the audience to learn independently. Without touching the national treasure, it will be presented in an "extra" interactive exhibit that integrates reality and reality. It cleverly uses HOPE's front internal cavity as "real" and the transparent display as "virtual". Through transparent projection technology and identification Interactive technology will present the introduction of cross-molecular beam instruments on a transparent interface, which will also be built as an interactive exhibit using direct-view AR augmented reality technology. For academician Yuen-Tseh Lee, the way to find answers to unknown questions is to design and make instruments by himself and found the answers in the spirit of scientific practice. Through the ongoing interactive exhibit of virtual and real integration, the audience can experience and operate it. The use of exhibition technology to present the experimental process should be conducive to the promotion of science popularization.
