摘要:
A subminiature pattern projector using rotational superposition of multiple optical diffraction elements is disclosed. A three-dimensional (3D) endoscope having the pattern projector is also disclosed. The 3D endoscope has a pattern projector that forms a pattern having high density and uniformity for acquiring a 3D image by using an angle offset between two or more optical diffraction elements. The pattern projector irradiates an optical diffraction pattern for shooting the 3D image, or includes a function as illumination for illuminating a region of interest in a human body.
