    • An intra-oral imaging apparatus for obtaining a contour image of a tooth has a fringe pattern generator energizable to emit a fringe pattern illumination. The fringe pattern generator has (i) at least one structured light source that is energizable to emit a patterned light beam; (ii) at least one reflective element in the path of the emitted patterned light beam and actuable to rotate about an axis to scan the emitted patterned light beam along a tooth surface as fringe pattern illumination. A detector is configured to acquire one or more images of the fringe pattern illumination from the tooth surface. A control logic processor is configured to control the fringe pattern generator for illuminating the tooth and to obtain and process the one or more images acquired by the detector.
    • 用于获得牙齿的轮廓图像的口内成像装置具有可激发的条纹图案发生器以发射条纹图案照明。 条纹图案发生器具有(i)可激发以发射图案化光束的至少一个结构化光源; (ii)在所发射的图案化光束的路径中的至少一个反射元件,并且可致动以围绕轴线旋转以沿着牙齿表面扫描发射的图案化光束作为条纹图案照明。 检测器被配置为从牙齿表面获取条纹图案照明的一个或多个图像。 控制逻辑处理器被配置为控制条纹图案发生器以照亮牙齿并获得并处理由检测器获取的一个或多个图像。
