    Bimodal endoscopic probe combining white-light microscopy and optical coherence tomography

    We present a novel bimodal endoscopic imaging probe that can simultaneously provide full-field white-light video microscopy and confocal optical coherence tomography (OCT) depth scans. The two modalities rely on spectrally separated optical paths that run partially in parallel through a micro-optical bench system, which has a cross-section of only 2   mm × 2.76   mm 2 mm×2.76 mm and is realized via standard silicon micromachining techniques. With a numerical aperture of 0.061, the video modality has a resolution and field of view of 9.3 and 1240   μm × 1080   μm 1240 μm×1080 μm , respectively. The resolution is ...
