Author Affiliations +
A zoom lens system using gradient-index lenses was studied to realize a compact video camera. This study investigates the relationship between the total index change and the amount of aberration correction in order to effectively apply existing gradient-index lenses to the zoom lenses. In addition, it examines how the effective dispersion of the gradient affects the chromatic aberrations while zooming. A zoom lens system consisting of a reduced number of lens elements using axial and radial gradient-index lenses is presented that can match the optical performance of a homogeneous lens system.
