摘要：
We present an analysis of the optical detection of two-dimensional vibration waves using two interferometric systems: a point-scanning heterodyne interferometer by optical reinjection (Laser Optical Feedback Imaging - LOFI) and a full-field stroboscopic Mach-Zehnder interferometer. We compare the spatial (resolution, sensitivity) and temporal (resolution, speed, bandwidth) performances for both vibrometers and discuss their application to photoacoustic imaging.
