Abstract
Suitable extraction of an object's wave field in an off-axis digital holographic array is the core for any numerical reconstruction process. In this manuscript, we propose an algorithm that reduces the number of pixels needed for an object's wave field trimming, reducing notably its processing time without significant changes in the quality of the reconstructed image. Our method generates an extraction window containing a complete object's wave field. The energy that the generated extraction window must contain is analyzed, defined, and used as a reference value. Our proposal reduces significantly the number of operations and execution time for holographic reconstruction.
