  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 and at least three camera
shots to reconstruct objects without the twin image and bias terms. In this
study, FINCH is realized using a randomly multiplexed bifocal binary Fresnel
zone lenses fabricated using electron beam lithography. A modified hologram
reconstruction mechanism is presented which introduces the single shot
capability in FINCH. A point spread hologram library was recorded using a point
object located at different axial locations and an object hologram was
recorded. The image of the object at different planes were reconstructed using
decorrelation of the object hologram by the point spread hologram library.
Application potential including bio-medical optics is discussed.
