Figure 1 | Lensless quantitative phase microendoscope: setup and concept.

Caption

(A) Microscopic image of the tip facet of the 10,000 core fiber bundle with a diameter of 350 μm. Scale bar 50 μm. (B) Photo of the multi-core fiber and a one euro coin for scale. (C) Conventional lensless microendoscopic imaging can only get the pixelated intensity information of the specimen, and the sample has to be very close to the fiber facet. (D) Quantitative phase and high-resolution amplitude images of the specimen can be reconstructed from the far-field speckle image. The sample can be placed far from the facet due to the digital focusing capability. (E) Experimental setup; SMF, single-mode fiber; MO, microscope objective; L, achromatic lens; LP, linear polarizer.
