N2 - At Baptist University, under the funding of a major industrial grant, we are developing the technology of digital speckle pattern interferometry (DSPI) for industrial sector. Our system fully exploits optical fibers and diode lasers in the design to enable practical and ruggedsystems suited for industrial applications. Besides the development in optics, we have developed a digital signal processing array system that can handle simultaneous and independent image capture/processing with feedback control. The system, named CASPA for 'cascadable architecture signal processing array', is a third generation development system that utilizes up to 7 digital signal processors has proved to be a very powerful system. With our CASPA we are now in a better position to developing novel optical measurement systems for industrial application that may require different measurement systems to operate concurrently and requiring information exchange between the systems. Applications in mind such as simultaneous in-plane and out-of-plane DSPI image capture/process, vibrational analysis with interactive DSPI and phase shifting control of optical systems are a few good examples of the potentials.
