    • Design of wide spectrum multi-sensor axis consistency detection system

    • 一项关于多传感器光电系统轴一致性检测的研究取得了重要进展。该研究针对传统检测系统工作波段范围较窄、系统灵活性较低的问题,创新性地结合了光路切换和光热转换的思想,设计了一套宽光谱多传感器轴一致性检测系统。该系统采用卡塞格林反射式光学系统,覆盖从可见光到长波红外范围,实现了宽光谱的检测能力。通过步进电机驱动导轨上方的反光镜位置移动,系统能够灵活切换光路,提高了系统的灵活性和适应性。同时,采用镀有硫化铜的锗玻璃作为光热转换靶材,将短波长的光斑转换为热斑,再用长波红外探测器实现对各波段激光光斑图像的采集,有效扩大了检测系统的光谱覆盖范围。研究团队对该检测系统进行了全面的性能评估。在0.4~14 μm波段光谱范围内,系统表现出良好的像质,由像差引起的弥散斑直径均在9 μm以下,能量集中度较高。此外,系统检测精度达到0.1 mrad,并通过导轨往返运动重复精度实验和系统测量准确度实验验证了系统的可靠性,结果表明检测系统满足仪表准确度1.5级的要求。该检测系统结构紧凑,适用波谱范围广,为多传感器光电设备的轴一致性检测提供了有效解决方案。这一研究成果在光电检测领域具有广泛的应用前景,为相关技术的发展和进步提供了新的动力。
