影像式模擬器應用已非常廣泛，其具有高安全性，經濟效益佳，重複使用性佳等優點；除了廣為人所知的飛行模擬器外，另有目標影像模擬器，用於飛彈電子影像導引系統的檢測。 本論文以DIME(Dynamic Infrared Missile Evaluator)為範本，設計一套適用於可見光波段的飛彈影像導引系統評估的模擬器；首先設計一套影像模擬器介面，以產生空中追擊目標的影像，同時標靶會產生多個目標以混淆飛彈導引系統，外在環境影像也可依需求改變。 平行光顯像系統對於飛彈測試相當重要，本文中討論了兩種形式的平行光鏡組，分別為折射式和反射式。折射式鏡組部份，介紹設計流程與成像品質評鑑，並完成平行光鏡組MTF=0.2 @ 45 lp/mm；反射式鏡組部份，則討論了影響成像品質的因素。最後整合了平行光鏡組與目標模擬器，建構出一套飛彈導引系統評估器。 The application of image type simulator is already widespread. It has advantages such as high quality of security, good economic efficiency and it performs well when being reused. Besides the well-known Aircraft Flight Simulator, there are target image simulator for the use of electronic-image guided missile guiding system examination. The present paper takes DIME (Dynamic Infrared Missile Evaluator) as an example for designing a simulator to be suitable for the missile image guiding system appraisal in visible light wave. First, design a set of image simulator to generate a target image for aerially pursuit. At the same time it would create many targets to confuse the missile guiding system. The external environmental image can be changed according to the demand as well. The collimating display system is quite important to the missile system test. This article discussed two kinds of collimating lens which are refractive type and reflective type respectively. In the part of refractive collimating lens, it introduced the design flow and the evaluation on imaging quality. As for the part of reflective collimating mirror, it discussed factors which influence imaging quality.
