Claim 10:
11. A system for generating a data structure that characterizes a near field illumination pattern generated by a light source, comprising:
a light source;
an imaging screen having one side, and having another side being opposite to the one side;
a positioning system for either or both of the imaging screen and the light source, the positioning system being for causing the imaging screen and the light source to have a one of a plurality of different relative position values each being separated by a mutual distance; and
an at least two-dimensional array illumination sensor for capturing, from at least one of the sides of the imaging screen when the imaging screen is illuminated by the light source, a plurality of two-dimensional arrays of luminance values collectively constituting a three-dimensional array of luminance values, each of the arrays of luminance values being correlated with a one of a plurality of two-dimensional arrays of image sensing positions, the plurality of the two-dimensional arrays of the image sensing positions collectively constituting a three-dimensional array of image sensing positions;
wherein the at least two-dimensional array illumination sensor and the positioning system are in communication with a processor for correlating each one of the plurality of the two-dimensional arrays of luminance values with a one of the plurality of different relative position values of the imaging screen and the light source, the processor being in communication with a storage system for storing a plurality of data structures, each one of the data structures representing a one of the plurality of the two-dimensional arrays of luminance values captured by the at least two-dimensional array illumination sensor and being correlated with a respective one of the plurality of different relative position values of the imaging screen and the light source.
