为了满足高分辨率红外成像的应用需求,设计了一种基于微扫描的红外超分辨率成像系统。该系统利用压电陶瓷驱动红外焦平面阵列实现微扫描,利用CPLD产生压电陶瓷和红外信号的驱动时序,利用高性能DSP进行实时图像数据的处理,并将处理后的图像送到LCD进行显示。实验结果表明,该微扫描成像系统能够实现2×2微扫描方式的超分辨率成像,有效地突破了红外焦平面阵列单元个数对现有成像系统的分辨率的限制。
In order to meet the application requirements of high-resolution infrared imaging, a micro-scanning infrared super-resolution imaging system is designed. The system uses piezoelectric ceramic to drive the infrared focal plane array to achieve micro-scanning. The system uses the CPLD to generate the driving timing of the piezoelectric ceramic and the infrared signal. The real-time image data is processed by the high-performance DSP, and the processed image is sent to the LCD for display . The experimental results show that the micro-scanning imaging system can realize the super-resolution imaging of 2 × 2 micro-scanning mode and effectively break the limitation of the resolution of the existing imaging system by the number of infrared focal plane array cells.
