His research interests have evolved over the years. He began with studies of the properties of antennas, microwave measurements, and microwave holography. These studies served as the foundation for subsequent projects such as the development of an ice surveying radar and a step frequency radar. With the advent of the laser, his studies shifted to the optical frequency range, where once again, his previous work on microwave phenomena served as an excellent foundation for the transition to optical phenomena. In the field of optics, his research includes optical measurement and sensor technology, fiber and integrated optics, the analysis of nonlinear guides, the invention of laser microvision and the Axi-Vision Camera, and 3D displays.
