Optical system for diffraction integration with a monochromatic plane-wave illumination. (ρ, φ) and (x0, y0) are coordinates in the IP-CZP plane, and (r, θ) and (x, y) are those in the observation plane at a distance z (= f + Δz) from the IP-CZP. l is the distance from a point Q in the IP-CZP plane to a point P in the observation plane. |
