國研院儀器科技研究中心(以下簡稱儀科中心)開發一套適用於讀取檢測紅外線發光二極體輸出光束形貌的裝置。筆者將介紹該方法之人機介面軟體，詳述影像處理方法及軟體功能。該系統以可見光攝影機取代紅外線熱影像儀，即可達成紅外線發光二極體輸出光束形貌讀取檢測的目的。本系統工作原理為利用可見光攝影機拍攝紅外線發光二極體輸出光束形貌，經螢光片與轉接機構，將基板上呈現之變色區域拍攝進來，最後，由電腦利用影像處理補償此基板與水平線所成之角度，則於電腦螢幕擷現出類似攝影機正面拍攝之圖樣，得到紅外線發光二極體元件之能量分布及資料。

We present an infrared LED inspector for beam spatial profile description. This paper is focused on the method of graphical user interface introductions， includes image processing and function. This system consists of the visible spectrum camera, a controled and analyzed NB， a phosphor plate， an inspector body and the tested LED fixture housing. The tested LED is turned on and emits the light on the phosphor plate， which faces the LED. The camera captures the output beam profile emitted from infrared LED on the phosphor plate. A computer program is designed to compensate the luminance relation versus the horizontal angle of the phosphor plate. The software automatically judges the output beam profiling of infrared LED. The image processing of this software includes ROI image processing， false-color image processing and power central distribution figure.
