  The correlation holography reconstructs 3D objects as a distribution of
two-point correlation of the random field detected by two dimensional detector
arrays. Here, we describe a hybrid method, a combination of optical and
computational channels, to reconstruct the objects from only a single pixel
detector. An experimental arrangement is proposed and as a first step to
realize the technique, we have simulated the experimental model for both scalar
and vectorial objects. Proposed technique affords background free imaging with
3D capability.
