System and method for diffractive image formation correction

摘要

An illumination modulation system for producing modulated illumination for an imaging system is disclosed. The illumination modulation system includes a first modulator and a second modulator. The first modulator receives illumination from an illumination source and produces modulated illumination. The second modulator receives modulated illumination and produces corrected modulated illumination for imaging. In various embodiments the second modulator may be passive or active.
