Re-sampling of continuous scanning LDV data for ODS extraction
The paper illustrates a re-sampling method for processing CSLDV data. CSLDV acquires simultaneously spatial and time information. CSLDV signals can be re-sampled with high spatial resolution, but aliasing occurs. The automatic recognition of aliased natural frequencies is presented. The automatic recovery of the actual un-aliased natural frequencies is presented. The ODS phase correction is done to take into account the un-synchronous acquisition.
