Claim 17:
18. A near-field characterization system comprising:
a light source for generating an illuminance pattern propagating in directions toward a translucent imaging screen;
the translucent imaging screen having a first side surface and having a second side surface being opposite the first side surface, the translucent imaging screen being disposed to receive the propagating illuminance pattern and to pass the illuminance pattern as received at the first side surface directly through the translucent imaging screen for lighting up the translucent imaging screen with the illumination pattern being visibly displayed on the second side surface;
a two-dimensional array illumination sensor disposed to capture the illuminance pattern lighting up the second side surface of the translucent imaging screen, the illuminance pattern including a two-dimensional array of luminance values being correlated with a corresponding two-dimensional array of image sensing positions;
a processor adapted to control the two-dimensional array illumination sensor and to store the two-dimensional array of luminance values as being correlated with the corresponding two-dimensional array of image sensing positions; and
a data storage facility that works with the processor to store the two-dimensional array of luminance values corresponding with the two-dimensional array of image sensing positions.
