WebFourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties. FTIR Scanning Microscope How does FTIR work? WebApr 17, 2024 · FDF-PIHD is low-cost and easy to implement without the need for additional wireless devices and the target to carry the related sensor devices. This scheme extracts the effective fingerprint in the frequency domain based on fine-grained physical layer information-CSI. The process is shown in Figure 4.
