Abstract
A method for non-contact modal analysis uses an optical sensing device such as a video camera. Unlike traditional modal analysis, requiring accelerometers or force sensors to measure the modal characteristics of a structure, the inventive system uses pixel displacement measurements from the optical sensor to characterize the modal properties of the device under test. The input or reference signal is measured by an independent data acquisition system and is synchronized with the response motion captured in video recordings.
