摘要： 为了提高实验型红外相机的灵活性和独立性，基于嵌入式技术设计了便携式红外相机，其拥有自己的微处理器、存储设备、显示设备和输入设备，可以脱离电脑的辅助独立运行。采用FPGA产生红外探测器和A/D转换器的时序。移植了Linux操作系统的ARM9微处理器，从现场可编程门阵列接收图像数据，在液晶显示器上显示图像，将图像数据存储到SD卡中。触摸屏作为输入设备用于接收用户的控制命令。

Abstract: To improve the agility and independency of experimental infrared camera, a portable infrared camera is built based on embedded technology. This camera can work without an assistant computer, because it has its own microprocessor, storage device, display device and input device. A Field Programmable Gate Array(FPGA) chip is used to generate the timing of infrared sensor and A/D converter. An ARM9 microprocessor chip, ported with Linux operating system, acquires the image data from FPGA, displayes the infrared image in a Liquid Crystal Display(LCD) and saves the data to a SD card. A touchscreen works as an input device to receive the user’s control instruction.
