This paper presents a new technique for evaluating a gradient-index rod lens that has a radial gradient index of refraction and can be used as an imaging or light-focusing device. The index profile is analytically related to imaging in terms of simple expressions for the aberrations. It is shown that the index profile can be easily checked by observing the distortion or field curvature of the image. A plastic gradient-index rod lens is evaluated by means of a proposed aberration-testing method, and the index profile is estimated.
