Abstract
A simple method for imaging vibrational motion is proposed. The process consists of capturing two speckled images of a region illuminated by coherent radiation. One of the images is captured before the onset of motion and the other during motion. If the mean speckle intensity is below the threshold for detection or above the saturation intensity of the detector, subtracting the two images produces a high contrast image of the moving region. A theory is shown to agree well with experimental data.
