Abstract
Light is projected from a light source in a first direction towards a tooth. The light source generates at least infrared light in the wavelength range of 950 nm to 2500 nm. A colloidal quantum dot (CQD) sensor records one or more surface light distribution images produced at the surface of the tooth by the projected light and the one or more surface light distribution images are used to compute a defect condition of the tooth.
Claims17
A method comprising:
- providing an intraoral camera comprising a light source;
- projecting light from the light source in a first direction towards at least one tooth, the light source is configured to generate at least infrared light in the wavelength range of 950 nm to 2500 nm, and visible light;
- recording, by a colloidal quantum dot (CQD) sensor, one or more surface light distribution images produced at the surface of the at least one tooth by the projected light, wherein the COD sensor is further configured to record color images in addition to recording the one or more surface light distribution images;
- and
- computing, using the one or more surface light distribution images, a defect condition of the at least one tooth.
An intraoral camera system comprising:
- a light source configured to generate at least infrared light in the wavelength range of 950 nm to 2500 nm, and visible light;
- a colloidal quantum dot (CQD) sensor;
- and
- a processor configured to:
- project light from the light source in a first direction towards at least one tooth;
- record, by the COD sensor, one or more surface light distribution images produced at the surface of the at least one tooth by the projected light, wherein the COD sensor is further configured to record color images in addition to recording the one or more surface light distribution images;
- and
- compute, using the one or more surface light distribution images, a defect condition of the at least one tooth.
A non-transitory computer readable storage medium storing one or more programs that when executed by a processor cause an intraoral camera to:
- project light from a light source of an intraoral camera in a first direction towards at least one tooth, the light source is configured to generate at least infrared light in the wavelength range of 950 nm to 2500 nm, and visible light;
- record, by a colloidal quantum dot (CQD) sensor, one or more surface light distribution images produced at the surface of the at least one tooth by the projected light, wherein the COD sensor is further configured to record color images in addition to recording the one or more surface light distribution images;
- and
- compute, using the one or more surface light distribution images, a defect condition of the at least one tooth.
