In this Letter we propose a fast off-axis hologram autofocusing (AF) approach that is based on the redundant data elimination by the critical resampling of the contained complex field. Implementation of the proposed methodology enables the real-time AF with up to 12× speed-up factors in comparison to the classical approach. The method is further extended for single-shot physical autofocus of the fluorescence imaging channel of multimodal imaging instruments capable of off-axis hologram acquisition.
在这封信件中，我们提出了一种快速离轴全息自动聚焦（AF）方法，该方法基于通过包含的复场的临界重采样消除冗余数据。与经典方法相比，所提出方法的实现能够实现高达 12 倍的实时 AF 加速。该方法进一步扩展为能够采集离轴全息的多模式成像仪器的荧光成像通道的单次物理自动聚焦。
