Design of an uncooled short-wave infrared core module based on ZYNQ
短波红外成像技术基于1~2.5 μm电磁波谱成像,无需依赖物体热辐射,受环境照度影响小,可弥补全波段成像空白,在多领域具有重要价值.文中设计基于ZYNQ平台与国产InGaAs焦平面探测器,开发非制冷短波红外机芯系统,实现图像采集、预处理与传输功能.硬件上设计主控板与驱动板,搭配 TEC温控、供电及外围电路,通过 Camera Link与以太网构建输出通道.软件上实现PL与PS端数据交互,基于JESD204B协议完成链路同步与数据接收,经改进预处理算法优化图像质量,最终实现640×512分辨率、30 f/s稳定输出,系统轻量化、低功耗且成本低,满足实际应用需求.
Short-wave infrared(SWIR)imaging technology,operating in the 1~2.5 μm electromagnetic spectrum,does not rely on ob-ject thermal radiation,is less affected by ambient illumination,fills the gap in full-band imaging,and holds significant value across mul-tiple fields.This design develops an uncooled SWIR camera core system based on the ZYNQ platform and a domestic InGaAs focal plane array(FPA)detector to realize image acquisition,preprocessing,and transmission:hardware encompasses a main control board,driver board,TEC temperature control,power supply,and peripheral circuits,with output channels established via Camera Link and Ether-net,while software achieves PL-PS data interaction,completes link synchronization and data reception based on the JESD204B protocol,and optimizes image quality through an improved preprocessing algorithm.The system achieves stable output of 640×512 resolution at 30 f/s,boasting light weight,low power consumption,and low cost,which fully meets practical application requirements.
