1. A simple matrix method for stray-light correction in an imaging instrument, comprising the steps of:

  • determining a set of point spread functions for the imaging instrument;

    deriving a stray-light distribution function for each of said point spread functions;

    based on the derived stray-light distribution functions, obtaining a stray-light distribution matrix; and

    deriving a stray-light correction matrix, including inverting the stray-light distribution matrix and an identity matrix.
