Abstract

See full text

A variable focal length (VFL) imaging system comprises a camera system, a first high speed variable focal length (VFL) lens, a second high speed variable focal length (VFL) lens, a first relay lens comprising a first relay focal length, a second relay lens comprising a second relay focal length, and a lens controller. The first relay lens and the second relay lens are spaced relative to one another along an optical axis of the VFL imaging system by a distance which is equal to a sum of the first relay focal length and the second relay focal length. The first high speed VFL lens and the second high speed VFL lens are spaced relative to one another along the optical axis on opposite sides of an intermediate plane which is located at a distance equal to the first relay focal length from the first relay lens. The lens controller is configured to provide synchronized periodic modulation of the optical power of the first high speed VFL lens and the optical power of the second high speed VFL lens.
