通过光纤成像束的同轴全息显微术

Inline holographic microscopy through fiber imaging bundles

Michael R Hughes

摘要:

光纤成像束被广泛地用作薄的、被动的图像导管,用于内窥镜和内窥镜显微术,特别是用于共焦荧光成像。通过光纤束的全息显微术更具挑战性;相位共轭方法很复杂,需要大量的校准。本文介绍了如何简单的内联全息显微镜可以通过成像束使用部分相干照明光源从多模光纤。样品在透射中成像,其中强度全息图由束采样并传输到远程相机。然后,全息图可以被数值重新聚焦的体积成像,实现约6微米的分辨率超过1毫米的深度范围。该计划不需要任何复杂的事先校准,因此是不敏感的弯曲。

英文摘要:

Fiber imaging bundles are widely used as thin, passive image conduits for miniaturised and endoscopic microscopy, particularly for confocal fluorescence imaging. Holographic microscopy through fiber bundles is more challenging; phase conjugation approaches are complex and require extensive calibration. This articles describes how simple inline holographic microscopy can be performed through an imaging bundle using a partially coherent illumination source from a multimode fiber. The sample is imaged in transmission, with the intensity hologram sampled by the bundle and transmitted to a remote camera. The hologram can then be numerically refocused for volumetric imaging, achieving a resolution of approximately 6 um over a depth range of 1 mm. The scheme does not require any complex prior calibration and hence is insensitive to bending.
