Abstract
Arrays of tapered light-guides enable the development of snapshot multi-dimensional imaging systems, such as containing wavelength information in addition to spatial (x,y) image intensity-distribution information. As a result of the tapered guides, the input and output of the array can have the same overall dimension while producing greater total inter-guide free space at the output plane than present at the input plane for the introduction of optical elements, such as dispersers, as needed for particular applications. Individual guides may be tapered at different rates within the array and the array itself may be tapered as a whole.
