description
"The various included datasets were accumulated during a project to experimentally validate the theoretical basis for the correction of SLDV measurements when subjected to base motion or instrument sensor head vibration. They complement the paper submitted to Mechanical Systems and Signal Processing on Jan 21, 2020 provisionally entitled "Establishing correction solutions for scanning laser Doppler vibrometer measurements affected by sensor head vibration".
There are a total of four Excel files, with content as follows:
UTSScanningBaseMotionCal_200918_new_Stash.xlsx - contains the accelerometer sensitivity check and time delay compensation processing set. This is the stage completed prior to the measurement campaign where the correction (and target if used) accelerometer performances are compared with the reference LDV for broadband (white noise) vibration.
UTSBenchtopScanningLDVBaseMotion_140918_new_v20Sept_Stash.xlsx - contains measured data for the scenario where the SLDV is used to measure the target vibration without any scan angles introduced. Vibration of both the target and the LDV are on axis. Various vibration levels of target and LDV are included (Off-L, L-Off, Off-H, H-Off, L-L, L-H, H-L, & H-H) with five averages for each result performed to minimise sources of experimental noise.
UTSBenchtopScanningLDVBaseMotion_140918_x_scan_v20Sept_Stash.xlsx - contains similar data to that of the previous file but only for H-L (LDV-Target) scenario but for LDV scan angles to result in laser beam steering in the x axis from -4 to +12 optical degrees in 2 deg. increments; 0 deg clearly duplicates the corresponding dataset for the no scan scenario and the processed results are identical as expected. The target vibration direction is aligned with the laser beam for all scan angles, i.e. the vibration is always on axis.
UTSBenchtopScanningLDVBaseMotion_140918_y_scan_v20Sept_Stash.xlsx - contains the same data as above but for laser beam deflection in the y direction."
