1. An image capture system comprising:
- a photosensitive medium for capturing an image;
a single path planar array located proximate to said medium for projecting light modulated with image information to the photosensitive medium, said array including a plurality of non-cylindrical concentrator elements formed in said array, said concentrator elements each having an input opening and an output opening and a reflective inner wall between each input opening and output opening which guides and concentrates said light towards and through an output opening towards said photosensitive medium for capturing said image, wherein for each of said elements, said input opening is larger than said output opening.

Abstract
A collector array for imaging comprises of a plurality of small concentrators having a hyperbolic cross section and a circular input and output aperture. Such an array is particularly suitable for use in conjunction with photoelectronic array-type detectors such as CCD'"'"'s and with photographic film.
