A direct method to reduce the recording time during the pulsed illumination in stroboscopic holographic interferometry is suggested. The technique involves increasing the recording time while the object is in static position and decreasing the recording time during the pulsed illumination accordingly while the object is vibrating. The approach is applied to double-exposure and triple-exposure cases of stroboscopic holographic interferometry, where it is found that considerable reduction in the recording time is possible.
