Reflective mode ASFPM image of a microprocessor chip. (a) Picture of the microprocessor. (b1–b2) Amplitude and phase of the reconstructed hologram. The hologram is digitally propagated to −3μm (c1–e1) and 2μm (c2–e2) away from the objective lens’ focal plane and three sub-regions are zoomed in. Intensity image captured with the aperture opened at NA=0.36 and microprocessor chip physically moved −3μm (c3–e3) and 2μm (c4–e4) are shown as a comparison to the digitally propagated results.
