| dc.description.abstract | 摘要
太空科學研究中常使用衛星上科學酬載的觀測資料，尤其在研究地球環境受到太陽風的影響，但衛星的成形需要龐大的資金、時間才能完成，因此近幾年立方衛星迅速發展，因為其製作時間短，成本低等優勢，其中影像是太空資料分析最主要的來源之一，所以製作系統化的立方衛星相機模組，簡化製作、實驗過程，能節省大量的開發時間。
本論文使用太空規格的影像感測器模組(Watec-T065)，在初步測試工作中使用TI MSP432微控制器提供影像感測器模組的控制訊號來測試影像感測器模組的各項功能，包含曝光時間的控制以及訊號的增益控制。影像資料為10bit，像素時脈為24.54 MHz，每張影像的有效像素659x494，曝光時間為1/60秒。在取像方面，我們初步使用數位邏輯分析儀將訊號擷取到電腦，並利用MATLAB將圖形繪製出來以驗證模組的影像功能。本實驗室也自行製作的影像擷取控制版，面積小於10×10 cm2，並且搭載太空規格的處理器SmartFusion2，並開發資料擷取的韌體，以提供將來應用於太空任務的影像感測器模組。

| dc.description.abstract | Abstract
Space science often uses the data obtained by the payloads onboard satellites, especially for those studies learning how the Earth’s environment is affected by the solar winds. A space mission requires a huge budget and is a very time-consuming task. Recently, the growth of Cubsat missions is rapid because of its advantage of low cost and first production. In Cubsat missions, image sensors are the primary payloads for remote sensing, which provides Earth’s images. Therefore, we developed an image sensor module to reduce the development time for future space missions.
In this work, we tested the control function of the microcontroller TI MSP432 for the image sensor. The CCD test setting includes the controls of exposure time and amplifier gain. The image sensor has an effective dimension of 659×494 pixels with a dynamical range of 10bit. The shortest exposure time can reach 1/60s. For image validation, we extracted the images using a digital logic analyzer and demonstrated the images using Matlab. Based on the test and validation, we developed an image capture circuit board with a physical size of < 10×10 cm2, which adopts a SmartFusion2 processor. This circuit board can be used for remote sensing and is qualified for future space missions.
