The analysis software is suitable for laser Doppler vibrometer (LDV). The software has a friendly user interface, providing FFT spectrum analysis, high pass, low pass, and bandpass filters. It can display real-time time-velocity curves, time-displacement curves, time-acceleration curves, etc. It can also record the vibration process and output UFF format files (which can be used for modal analysis), making it convenient for customers to analyze and process. 1. Single channel (time-domain and frequency-domain): suitable for measurement with a one-dimensional laser vibrometer; 2. Dual channel (time-domain and frequency-domain): suitable for axis trajectory, two-dimensional measurement, swing angle measurement, etc. on rotating machinery; 3. Multi channel (time domain and frequency domain): suitable for 3D measurement, multi freedom measurement, etc.
