Accuracy of 3D image manipulation through linear transformation of wide-angle hologram

Methods for manipulating the geometry of 3D image by linear transforming of hologram data are very efficient. Such techniques are desirable also for wide-angle viewing holographic display. Especially when there is no direct access to the reconstructed image due to lack of numerical hologram reconstruction techniques. Hence, methods based on directly manipulating the holographic image cannot be applied. In this paper, we investigate theoretically, numerically, and experimentally the image manipulations based on hologram stretching for the case of wide-angle near eye holographic display. We show that for wide-angle display the significant Petzval curvature and astigmatism errors are obtained in image reconstruction. Finally, applicability of the investigated image manipulation methods is shown with experiments of hologram reconstructions in a wide-angle holographic display.
