  • Abstract
    An adaptive focusing (AF) algorithm based on minimum-entropy (ME) method is proposed for THz single frequency holography to improve the depth of focus for practical image applications. Experiments in 0.2THz band were performed to confirm the effectiveness of the proposed algorithm.
