中文摘要：
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。
英文摘要：
In order to satisfy the application requirements of high-resolution infrared imaging,an infrared super-resolution imaging system based on micro-scanning was designed.The system uses piezoelectric（PZT）-driving infrared focal plane array（IRFPA）to realize microscanning,and uses CPLD to generate the driving timing sequence of PZT and infrared signal,and image data can be processed in real time by using high performance DSP,thus processed images are sent to LCD for display.Experimental results show that the micro-scanning imaging system can realize super-resolution imaging of 2×2 micro-scanning method,and effectively break through the limit of IRFPA unit number in existing imaging systems.
