A radiation responsive detector arrangement for use with a range determination system. A first plurality of detector pairs are mounted to receive radiation from a lenslet array which produces a plurality of images of the exit pupil of a first objective lens whose f number is equal to or less than a predetermined value and a second plurality of detector pairs are mounted to receive radiation from the lenslet array which produces a plurality of images of the exit pupil of a second objective lens whose f number is greater than the predetermined value. Switch means is provided so as to use the outputs of the first plurality of detector pairs in the range determination system when the first objective lens is employed and to use the outputs of the second plurality of detector pairs in the range determination system when the second objective lens is employed.

A detector arrangement for use with an optical system including; an objective lens for producing an image of a remote scene at a first image plane; a plurality of lenslets mounted proximate the first image plane for producing a plurality of images of the exit pupil of the objective lens at a second image plane, the image of the exit pupil having a first size when the objective lens is of a first f number and a second size when the objective lens is of a second f number; and a first and second plurality of pairs of detectors mounted proximate the second image plane, the size of the first plurality of pairs of detectors being chosen so that the radiation sensing portion of each pair may closely fit entirely within a different one of the images of the exit pupil of the first size and the size of the second plurality of pairs of detectors being chosen so that the radiation sensing portion of each pair may closely fit entirely within a different one of the images of the exit pupil of the second size.
