Abstract:	摘要： AbstractLimited by the penetration depth, imaging of thick bio-tissues can be achieved only by epi-detection geometry. Applications based on forward-emitted signals or bidirectional illumination are restricted by lack of an opposite objective. A method for creating an opposite virtual objective inside thick media through phase conjugation was first proposed. Under forward illumination, the backward scattering light from the media was collected to generate a phase conjugate wave, which was sent back to the media and formed an inverse focusing light. Samples combined with a diffuser or a mouse skin were used as specimens. Inverse focusing was successfully demonstrated by applying holography-based optical phase conjugation with a BaTiO3. This result indicates the capability to create an opposite virtual objective inside live tissues. The proposed method is compatible with current coherent imaging and super-resolution imaging technologies. It creates a possible way for forward-emitted signals collection and bidirectional illumination in thick specimens. 其他題名： Sci Rep 出版者： London: Springer Science and Business Media LLC 出版日期： 2016-07-11 出處： Scientific Reports, 2016-07, Vol.6 (1), p.29452-, Article 29452 資源來源： Nature Journals Online 版權： The Author(s) 2016 版權： Copyright Nature Publishing Group Jul 2016 版權： Copyright © 2016, Macmillan Publishers Limited 2016 Macmillan Publishers Limited 識別號： ISSN: 2045-2322 識別號： EISSN: 2045-2322 識別號： DOI: 10.1038/srep29452 識別號： PMID: 27404383
