Abstract
Locating objects that vibrate is a way to discern potential threats and locate targets. However, current vibrometry technology typically measures only the global vibration of target and cannot create an extended spatial measurement of the vibration profile of the target. These solutions cannot identify what the target is, nor can they locate potential weak spots on the target, because they lack spatial information about the target. Guidestar is proposing to generate spatial vibrometry images using a digital holography system. By sampling at high rates, the target information captured using digital holography can be used to compute a vibration image. The vibration measurements will be extracted from phase signals heavily degraded by scintillation and speckle using UCLA system identification and filtering algorithms. By combining Guidestars expertise in optical systems and real time processing and UCLAs signal processing and filtering techniques, the proposed approach will seek to generate reliable full vibration target images of simulated target imagery.
