Abstract

Single element detection, spatial frequency modulation imaging (SPIFI) is deployed in a laser processing environment. SPIFI images are used to monitor a laser melting process, like that encountered during additive manufacturing, with an exposure time of 120μs, which enables real-time, in-situ monitoring of melt track formation coaxial with the processing laser. SPIFI images from a single photodiode are shown to be comparable to or better than white light camera images taken at the same numerical aperture. SPIFI deployed in this manner represents a disruptive new sensor metrology system that, when coupled with developing process models, can ultimately be used to validate statistically significant process parameter-signature-quality relationships with quantified uncertainty.

用于激光加工应用的空间频率调制成像技术
在激光加工环境中部署了单元素检测、空间频率调制成像(SPIFI)。SPIFI 图像用于监测激光熔化过程,就像增材制造过程中遇到的情况一样,曝光时间为 120μs,从而能够实时、原位监测与加工激光器同轴的熔化轨迹的形成。来自单个光电二极管的 SPIFI 图像可与相同数值孔径下拍摄的白光相机图像相媲美,甚至更好。以这种方式部署的 SPIFI 是一种颠覆性的新型传感器计量系统,与开发中的工艺模型相结合,最终可用于验证具有统计意义的工艺参数-信号-质量关系,并量化不确定性。
