Abstract
A remote sensor capable of imaging vibrations at many simultaneous points using high-speed imaging cameras is disclosed. The preferred embodiment operates in heterodyne detection mode using a single camera to capture signals to recover multi-pixel vibrations. One alternative embodiment employs two cameras and homodyne optical I/Q detection. A second alternative embodiment uses a single camera and temporally phase shifted local oscillator to also carry out homodyne optical I/Q detection. The disclosed sensors are capable of scalability to large numbers of pixels and can capture vibration frequencies over a wide range.
