3-轴传感器

对IEEE1451 标准中的智能传感器功能模型和信息模型进行了具体分析, 并且结合网络化智能传感器通用开发平台 的设计实现的体验, 对IEEE1451 的设计思想做出评价。IEEE1451 标准成功之处是对变送器电子数据表T EDS 的设计, 较好 地解决了传感器自动校正的问题。IEEE1451 智能传感器信息模型是一个通用模型, 但在实现上有一定难度, 缺乏功能相对简 单的模型子集。另外, IEEE1451 标准把智能传感器划分为ST IM 和NCAP 两个模块, 必要性不强。最后讨论了智能传感器标 准的未来发展。

Image sensors have recently attracted renewed interest for use in digital cameras, mobile phone cameras, handy camcoders, cameras in automobiles, and other devices. For these applications, CMOS image sensors are widely used because they feature on-chip integration of the signal processing circuitry. CMOS image sensors for such specific purposes are sometimes called smart CMOS image sensors,vision chips,computational image sensors, etc. Smart CMOS Image Sensors & Applications focuses on smart functions implemented in CMOS image sensors and their applications. Some sensors have already been commercialized, whereas some have only been proposed; the field of smart CMOS image sensors is active and generating new types of sensors. In this book I have endeavored to gather references related to smart CMOS image sensors and their applications; however, the field is so vast that it is likely that some topics are not described. Furthermore, the progress in the field is so rapid that some topics will develop as the book is being written. However, I believe the essentials of smart CMOS image sensors are sufficiently covered and that this book is therefore useful for graduate school students and engineers entering the field. This book is organized as follows. First, MOS imagers and smart CMOS image sensors are introduced. The second chapter then describes the fundamental elements of CMOS image sensors and details the relevant optoelectronic device physics. Typical CMOS image sensor structures, such as the active pixel sensor (APS), are introduced in this chapter. The subsequent chapters form the main part of the book, namely a description of smart imagers. Chapter 3 introduces several functions for smart CMOS image sensors. Using these functions, Chapter 4 describes smart imaging, such as wide dynamic range image sensing, target tracking, and three-dimensional range finding. In the final chapter, Chapter 5, several examples of applications of smart CMOS image sensors are describe
