本計畫發展出一套使用高速攝影機配合影像處理技術之高速瞬時面流場量測系統。此高速質點影像測速儀係使用連續型雷射光源並以光頁產生器形成雷射光頁來照明流場,以使低照度之高速CCD攝影機能擷取質點運動軌跡從而求取全面瞬時流場訊息。獨一的影像處理軟件乃運用交關法於處理、分析、計算與立體展現流場訊息;而完成研發一套快速、簡單且經濟的高速瞬時面流場量測系統。 The goal of this study is to develop a high-speed global flow-field measurement system. This new developed particle image velocimeter employs a continuous mode laser, a laser sheet projector, a high frame-rate, low-lux CCD camera and a promising image-processing cross-correlation system to provide a simple, fast and inexpensive method to obtain the instantaneous full-field velocity information for the high-speed flow.
