中文摘要 | 本文討論一個採用 MOS-微電阻陣列所構成之紅外線影像產生器系統。MOS-微電阻 陣列係由目前商用之矽晶片製程所製成,每一微電阻(約 5 mil x 5mil 大小)可以分別由 一精確電流控制加熱到 1300 ° K 內任一溫度,此種技術之優點在於高解析度, 高信號動 態範圍,快速反應以及易於大量生產。所以它很適合用來產生真實快速移動之紅外線動態影 像。 文中討論對於此陣列之控制,同時一個原型系統亦試製完成,並附上測試結果。 由於 MOS- 微電阻陣列本身之非線性與非均質性特性, 所以系統設計時考量二種校正方法,分別 是全查表法與區段查表法。考量系統精確度要求,故實作時採用全查表法。 |
英文摘要 | An infrared scene generator system based on MOS-resistor array technolog y is presented. The MOS-resistor array is fabricated using a commercially available Si process. Each resistor (5milX5mil per pixel) is independently heated to any desired temperature up to 1300 ° K by an accurately controlled pulsed current. The MOS-resistor array has the characteristics of high resolution, high dynamic range, fast response and ease of manufacture, which can generate a realistic, fast-moving IR scene. In this paper, the control issues of an ifrared scene generator system using a MOS-resistor arrayare discussed. Finally, a prototype for a dynamic infrared scene generator system is built and reported here. due to the inherent nonlinearity and nonuniformity characteristics of the MOS-resistor array, two methods are proposed: the full lookup table and the segmented lookup table. The prototype system used full lookup table approach for more accuracy. |
