  • Multiwave dental imaging system
    Patent number: 11455721
    Abstract: An imaging system comprises multiple light sources, a beam combiner, an optical array sensor, and a computing device. A first light source forms a first beam of light at a first wavelength. A second light source forms a second beam of light at a second wavelength. The beam combiner combines the first beam of light and the second beam of light into a single beam of light and illuminates a specimen with the single beam of light. The optical array sensor detects reflected light that is reflected from the specimen. The computing device accesses sensor data from the optical array sensor, forms a first image based on the first wavelength and a second image based on the second wavelength, and forms a composite image from the first image and the second image.
