英文摘要 | a new subminiature endoscope which used for reconnaissance and diagnosis has been designed. this subminiature endoscope is designed based on imaging fiber bundle and consist of the front object lens whose aperture is only 0.5mm, imaging fiber bundle and the post coupling lens. it realized by using subminiature optical systems. the fov(field of view) and the focal length of the front object lens are 50 degrees and 0.59mm. and the object distance, f number and detected imaging high of the front object lens are 3mm, 6 and 0.5mm. the total number of the imaging fiber bundle are 10000 and it's pixel cell size is 5 mu m. the effective aperture of the imaging fiber bundle is 0.46mm. the post coupling lens has a reduction ratio of 1.73. it's object distance and imaging height are 5mm and 0.8mm. the numerical aperture (na) of the front object lens, imaging fiber bundle and the post coupling lens are matching will. the coupling efficiency of the imaging fiber bundle is above 93% and the system's design result can meet the need of the limit resolution of the imaging fiber. this kind of the fiber endoscope has the peculiarity of wide fov, fine imaging quality, compact configuration, low finished cost and etc. it is meaningful to realize the objective of miniaturization, batch-type production and high imaging quality of the endoscope. |
