The imaging characteristic of a curved (curvature ρ) light-focusing plastic rod (LFR), with a constant quadratic gradient of refractive index and radius rp is examined. It was found that curving a LFR produces limitation in the image field, and that the extent of the limiation is inversely proportional to arpρ according to a relation derived theoretically. In the case of a partially curved LFR, the image location was found to shift periodically with increase in the curved portion.
