    For many years, Dr. Nagaoka and his group have been engaged in the research and development of devices for image engineering and applied optics. During this time, Dr. Nagaoka and his group has achieved numerous groundbreaking results in the mass-production of aspherical lens based on glass molding method for cameras and disks, also has contributed to the advancement of Television technology by promoting the EDTV-II system through the practical usage of a high performance low cost progressive scanning camera.

    In recognition of his outstanding achievements in these fields, Dr. Nagaoka (Panasonic Corp.) was awarded the “Niwa- Takayanagi Award’s Achievement Award” in 1994 by the Institute of Television Engineers of Japan.
