美国Quest Qi2 MOI+ (Magneto-Optic Imaging System)
For 20 years Magneto Optic Imaging (MOI) has been pivotal in increasing use and life extension of aircraft structures. MOI is a highly effective and efficient non-destructive evaluation (NDE) process that can be used to detect surface and sub-surface cracks in aircraft skin near fasteners, as well as sub-surface corrosion. Using eddy current excitation, the MOI’s rapid scanning process enables aircraft inspectors to observe greater flaw detail, and greatly reduces downtime for required inspections. Qi2 is excited to announce our latest and most advanced MOI system, the MOI+. In our latest design, we have
- Replaced the analog controls with digital interface
- Replaced the Heads-Up display (headset) with an LCD monitor that can be attached to the imager or hand-held
- Reduced the imager size while maintaining a large 45mm field of view (FOV)
- Added digital video output to facilitate recording of inspections
- Enhanced the video quality
20年来, 磁光成像 (MOI) 在飞机结构的使用和延长寿命方面起着举足轻重的作用。MOI是一种高效有效的无损评估方法, 可用于检测紧固件附近飞机皮肤表面和表层的裂纹, 以及表层腐蚀。通过使用涡流激发, MOI的快速扫描过程使飞机检查人员能够观察到更大的缺陷细节, 并大大减少了所需检查的停机时间。Qi2 兴奋地宣布我们最新的和最先进的MOI系统, MOI +, 在我们最新的设计中，我们有：
•用数字接口Replaced 模拟控制
•Replaced 的头上显示 (耳机) 与 LCD 显示器, 可以连接到成像器或 hand-held
•Reduced 的图像大小, 同时保持一个大的45mm 视野 (视)
•Added 数字视频输出, 方便记录检查
•Enhanced 视频质量
MOI Advantages
- Calibration not required
- Significant time savings in inspections
- Minimal operator training required
- Paint stripping or protective coating removal not required
- Rapid real-time inspection of large areas
- Demonstrated 10 times faster than eddy current probes alone
