This paper is concerned with vibration deflection-shape measurement techniques for a sinusoidally excited structure, using a continuously scanning laser Doppler vibrometer (CSLV). The CSLV output signal is an amplitude-modulated vibration in which the excitation signal is modulated by the (complex)
