摘　　要： 目的探讨图像传感器在体内无线内窥微机电系统的应用。方法比较不同类型图像传感器的优缺点,并考虑体内的使用环境和要求,选择集成度高、功耗低、体积小,可输出模拟图像的CMOS图像传感器作为无线内窥微机电系统的传感部件,对此类传感器的特定型号的体积和功耗进行比较分析。结果本设计合理解决了设计图像传感器外围电路时应该注意的接地、晶振电路配置、电路板布线等问题,制造出了含OV7930的图像传感器采集模块,在动物实验中成功采集到图像。结论在无线内窥微机电系统中关于此图像传感器的应用设计是可行的。 Objective To discuss the application of image sensor in wireless endoscopic micro-electro-mechanical system （MEMS）. Methods Through the comparison of various types of image sensors, and in the consideration of the environment and requirement inside the body, CMOS image sensor which can output analog image signal with high density of integration, low power consumption, small profile was chosen as the sensor component of a wireless endoscope. The profile and power consumption of some specific models of this type of image sensor were compared and analyzed. Results The problems, such as ground connection, crystal configuration and the layout of circuit board, were reasonably solved during the design of im- age sensor＇s schematic circuit diagram. The image capture module based on OV7930 sensor was designed and manufactured. Images were successfully captured during the animal experiments. Conclusion The application and design of image sensor in a wireless endoscopic MEMS are feasible.
