摘要
En 中文
• A multi-fiber sensor decodes respiratory motion into spatiotemporal light patterns. • A peak-detection and grayscale algorithm is integrated for information extraction. • Respiratory amplitude measurement within individual cycles with a linearity of 0.993. • Respiratory rate estimation within individual cycles with an error of less than 4%.
