Fresnel incoherent correlation holography with single camera shot

Blog Article

Fresnel incoherent correlation holography (FINCH) is a self-interference based super-resolution three-dimensional imaging technique.FINCH in inline configuration requires an active phase modulator to record at least three phase-shifted camera shots to reconstruct objects without twin image and bias terms.In this study, FINCH is realized Queen/Full Panel Headboard using a randomly multiplexed bifocal binary diffractive Fresnel zone lenses fabricated using electron beam lithography.

The object space is calibrated by axially scanning a point object along the optical axis and recording the corresponding point spread holograms (PSHs).An object is mounted within the calibrated object space, and the object hologram 3 Piece Sectional with Cuddler was recorded under identical experimental conditions used for recording the PSHs.The image of the object at different depths was reconstructed by a cross-correlation between the object hologram and the PSHs.

Application potential including bio-medical optics is discussed.
