Title:
INTRAORAL MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2022061258
Kind Code:
A
Abstract:
To provide an intraoral measuring device capable of highly precisely measuring a shape regardless of a further simple device configuration in a configuration using a prism.SOLUTION: An intraoral measuring device includes a light projection system applying floodlight, an imaging system receiving imaging light formed by reflecting the floodlight by a measuring object, and a prism being disposed on an optical path between the light projection system and the imaging system, guiding the floodlight applied from the light projection system to the measuring object and guiding the imaging light formed by reflecting the floodlight by the measuring object to the imaging system. The prism is configured to define an incidence plane of the floodlight and an exit plane of the imaging light as a same light transmission surface and to define an exit plane of the floodlight and an incidence plane of the imaging light as a same imaging surface disposed facing the measuring object. An optical axis of the imaging system is parallel to a normal line of the light transmission surface and a normal line of the imaging surface in the prism.SELECTED DRAWING: Figure 3
