1. A method of deriving increased information from electromagnetic energy, said method comprising:
- determining values of any of several spatial phase characteristics of the electromagnetic energy; and
using the determined spatial phase characteristic values in a manner to provide information;
wherein said step of determining values of any of several spatial phase characteristics of the electromagnetic energy includes determining at least one spatial phase characteristic value at each of a plurality of point elements of an image plane associated with the electromagnetic energy, and said step of using the determined spatial phase characteristic values in a manner to provide information includes using differences in the determined at least one spatial phase characteristic values at each of a plurality of point elements to generate an image.

8. A method of deriving increased information from electromagnetic energy, said method comprising:
-
determining one quantitative-existence value related to at least one spatial phase characteristic of the electromagnetic energy for one portion of electromagnetic energy;
determining another quantitative-existence value related to at least another spatial phase characteristic of the electromagnetic energy for the one portion of electromagnetic energy or the one spatial phase characteristic of the electromagnetic energy for another portion of electromagnetic energy;
quantifying the one quantitative-existence value relative to the other quantitative-existence value; and
using the quantification of the one quantitative-existence value relative to the other quantitative-existence value as information. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
