The holographic facial profile scan is a new technique for creation of high-resolution, three-dimensional, realistic facial computer models which can be used for surgical planning and documentation in maxillofacial surgery. First, a holographic image of the patient is recorded using a pulsed laser system. In a second step, called holographic tomography, the real image of the patient's hologram is reconstructed by means of a continuous-wave laser. By moving a screen through the real three-dimensional image, it is sliced into a series of two-dimensional projections which are captured with a digital camera. The slices containing the specific two-dimensional information are superimposed to a three-dimensional surface model using special software. The extremely short exposure time of 35 nanoseconds for taking a holographic image is separated from the time-consuming rendering process of the surface model; thus, the obtained models are not affected by the movements of the patient.
全息面部轮廓扫描是一种用于创建高分辨率、三维、逼真的面部计算机模型的新技术，可用于颌面外科手术的规划和记录。首先，使用脉冲激光系统记录患者的全息图像。在第二步，即全息断层扫描中，通过连续波激光重建患者全息图的实像。通过将屏幕移动通过真实的三维图像，将其切成一系列二维投影，并用数码相机捕获。使用特殊软件将包含特定二维信息的切片叠加到三维表面模型上。拍摄全息图像的35纳秒极短曝光时间与表面模型耗时的渲染过程分开；因此，获得的模型不受患者运动的影响。
