In off-axis configuration, with a slow camera and a laser diode, holographic interferometry is sensitive enough to enable wide-field, laser Doppler imaging of optical fluctuations in amplitude and phase, either with a slow or a fast camera. A slow (e.g. video rate) camera will record time-averaged holographic interferograms which will result in lowpass filtering of the optical fluctuation signal. By shifting the frequency of the reference beam, the lowpass filter becomes a bandpass filter centered at the detuning frequency, and selective narrowband detection and imaging can be performed.
