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.
