Embodiment Construction
[0071] The present invention proposes an endoscopic imaging system and method based on a single multimode optical fiber, which is divided into two parts: an imaging system and an imaging method. Figures 1 to 6 Introduce them one by one.
[0072] Part 1: Imaging system (such as figure 1 shown)
[0073] The endoscopic imaging system based on a single multimode optical fiber of the present invention includes an illumination system, a light field measurement system and a computer processing system 11 .
[0074] The illumination system is used to provide a linearly polarized laser light source, including a laser 1 , an optical attenuator 2 , a collimator beam expander 3 and a first linear polarizer 4 arranged in sequence.
[0075] The light field measurement system is an interference optical path, including a beam splitter 5, a reference arm, an object light arm, a second linear polarizer 9 and a camera 10; the beam splitter 5 is used to divide the laser light source output by t...
