Zooming algorithms for digital holography
Optional Fields
Digital Holography is an imaging modality made up of two parts: (i) Recording an interference pattern on a CCD, where an object wave field and a known reference wave are coincident and extracting the complex object wave field from this interference pattern and (ii) Replaying or reconstructing the hologram on a computer by simulating the propagation of the object wave field back to the object plane. Thus an image is obtained. We show how to adapt the reconstruction algorithm in a simple way to allow it to generate any output range and in any location making it far more versatile for zooming in on specific regions of our reconstructed image. © 2010 IOP Publishing Ltd.
