Abstract

PURPOSE: A three dimensional endoscope system is provided to use an optical fiber for an optical image transferring unit of an endoscope center for minimizing a lowering of a resolution. CONSTITUTION: A stereoscopic endoscope system by using an optical inverse filter is composed of:a couple of substance lenses group(20) being formed by a left eye substance lens(20a) and a right eye substance lens(20b); an optical image transferring unit(30) being formed by a left eye optical fiber body(30a) and a right eye optical fiber body(30b); an optical inverse filtering unit(40, 50) operating optically an inverse filtering to the optical image being transferred by the optical fiber bodies(30a, 30b); an image sensing unit(60, 70) receiving the output of the optical inverse filtering unit(40, 50) for electrically coupling through a photoelectric transform; and reflecting mirror unit(80, 90) for changing an optical route for the optical image to face the optical inverse filtering unit. Therefore, this device can reduce the diameter of the endoscope while transmitting the optical image of a high resolution.
