Abstract
A miniaturized spectrometer/spectrophotometer system and methods are disclosed. A probe tip including one or more light sources and a plurality of light receivers is provided. A first spectrometer system receives light from a first set of the plurality of light receivers. A second spectrometer system receives light from a second set of the plurality of light receivers. A processor, wherein the processor receives data generated by the first spectrometer system and the second spectrometer system, wherein an optical measurement of a sample under test is produced based on the data generated by the first and second spectrometer systems.
Claims19
A method for determining optical characteristics of an object comprising:
- storing a plurality of dental shades;
- calibrating the stored plurality of dental shades by measuring optical properties of a test object;
- measuring a shade of the object with an instrument;
- comparing the measured shade of the object to the calibrated shades;
- determining one or more shade match candidates from the stored dental shades, according to the comparing;
- and
- displaying the one or more shade match candidates on a display device.
A system for determining optical characteristics of an object comprising:
- a memory for storing a plurality of dental shade system each dental shade system including a plurality of shades;
- an optical measurement unit for measuring optical properties of the object;
- a calibration block for calibrating the optical measurement unit by measuring optical properties of a test object;
- a processor for comparing the measured optical properties of the object to the stored plurality of shades, and for determining one or more shade match candidates according to the comparing;
- and
- a display for displaying the one or more shade match candidates.
