Abstract:
1. A method for determining optical properties of a dental object, the method comprising; receiving reflected light from the dental object by a first light receiver, a second light receiver and a third light receiver, simultaneously in a single measurement, wherein the first light receiver is a center light receiver and the second light receiver includes a plurality of light receivers configured in a ring configuration, wherein the first light receiver is coupled to a randomized fiber optic and the second light receiver is coupled to a light pipe that is different than the randomized fiber optic; generating, by a spectrometer, first data based on reflected light received by the first light receiver and second data based on light received by the second light receiver; generating topology information from the light received by the third light receiver; when the dental object is a natural tooth, applying, by a processor, a first weight factor to the first data received by the first light receiver and a second weight factor to the second data received by the second light receiver; when the dental object is a dental restoration, applying, by the processor, a third weight factor to the first data received by the first light receiver and a fourth weight factor to the second data received by the second light receiver, wherein the first weight factor is different than the third weight factor and the second weight factor is different than the fourth weight factor; and determining, by the processor, optical properties of the dental object, responsive to applying the first weight factor and the second weight factor to the first data and the second data or applying the third weight factor and the fourth weight factor to the first data and the second data.
