顾名思义，扫描仪就是用来对物体进行扫描的工具，通过扫描我们可以得到物体的成像。
但是其他产品和工具一样，扫描仪的种类也是多样的，并且不同种类的扫描仪特点和优势也各不相同。
今天我们就一起来了解一下在扫描领域比较先进的三维激光扫描仪。
下面将从不同类型的三维激光扫描仪有哪些特点和优势给大家进行简单的介绍。
三维激光扫描仪按照扫描成像方式的不同，激光扫描仪可分为一维(单点)扫描仪、二维(线列)扫描仪和三维(面列)扫描仪。
而按照不同工作原理来分类，可分为脉冲测距法（亦称时间差测量法）和三角测量法。
1、脉冲测距法：激光扫描仪由激光发射体向物体在时间t1发送一束激光，由于物体表面可以反射激光，所以扫描仪的接收器会在时间t2接收到反射激光。
由光速c，时间t1，t2算出扫描仪与物体之间的距离d=(t2-t1)c/2。
脉冲测距式3D激光扫描仪，其测量精度受到扫描仪系统准确地量测时间的限制。
当用该方式测量近距离物体的时候，由于时间太短，就会产生很大误差。
所以该方法比较适合测量远距离物体，如地形扫描，但是不适合于近景扫描。
2、三角测距法：用一束激光以某一角度聚焦在被测物体表面，然后从另一角度对物体表面上的激光光斑进行成像，物体表面激光照射点的位置高度不同，所接受散射或反射光线的角度也不同，用CCD （图像传感器）光电探测器测出光斑像的位置，就可以计算出主光线的角度θ。
然后结合己知激光光源与CCD 之间的基线长度d，经由三角形几何关系推求扫描仪与物体之间的距L≈dtanθ。
手持激光扫描仪通过上述的三角形测距法建构出3D图形：通过手持式设备，对待测物发射出激光光点或线性激光。
以两个或两个以上的侦测器测量待测物的表面到手持激光产品的距离，通常还需要借助特定参考点－通常是具黏性、可反射的贴片－用来当作三维扫描仪在空间中定位及校准使用。
这些扫描仪获得的数据，会被导入电脑中，并由软件转换成3D模型。
3、三角测量法的特点：结构简单、测量距离大、抗干扰、测量点小（几十微米）、测量准确度高。

Brilliant.“Smart robotic assistance.Get in position to take control.Digitally connected workflow.Take advantage of integrated efficiency.Tracking distances positioning made easy.Ultrasound sensors assist in actuating the robotic arms. Integrated top-view, side-view and therapy cameras allow you to intelligently observe the surgical environment between device and patient. You are able to observe the patient with ease and ergonomic comfort while docking the cornea correctly.CentraLign systemfor easy centration with little effort.The CentraLign ® assistant system is a computer-controlled function for easy centration. It uses pupil center and vertex position, giving you full control of centration already during the docking phase. There is no need to shift the cutting pattern after docking.Scan the QR code to watch the simulation.OcuLign systemfor easy cyclotorsion alignment.ZEISS VISUMAX 800 features the intuitive OcuLign ® pattern rotation. The sophisticated yet easy-to-use system automatically re-calculates the treatment pattern and helps to counter cyclotorsion that may occur.Scan the QR code to watch the simulation.The VISUMAX 800 connects seamlessly with different products and solutions from ZEISS. The reliable integration can help you achieve faster procedures and more efficiency in a streamlined workflow while assisting you in reducing sources of error.ZEISS Refractive WorkplaceEasily manage, evaluate, store and transfer data.VISUMAX 800 connects to the powerful Refractive Workplace software 5, which runs on the FORUM ® data management solution from ZEISS. Before and after laser vision correction treatments, all relevant surgical procedure documentation, including all videos, is assigned to each respective patient, and stored after confirmation in ZEISS FORUM. You can streamline your workflow and carry out patient data management and treatment planning from anywhere in your clinic. Additionally, you get support in reducing the amount of administrative tasks performed inthe OR.Easy patient access with comfort and control.From the start of a procedure, ZEISS VISUMAX 8001 makes the surgical experience comfortable and reassuring for everyone in the OR. While patients comfortably lie on the surgical bed, you can access patients without difficulty. And as soon as the patient is situated properly, the arm required can be brought into working position – either the laser arm or the OPMI arm for manual surgery.Intelligent robotic assistant systems, such as cyclotorsion and centration aid, can help in enhancing control during your procedures. In every way, the device has been designed to deliver state-of-the-art performance that adds efficiency and ergonomics.5 CE certification Refractive Workplace planned in 2022.Streamline your refractive workflow.The new ZEISS Corneal Refractive Workflow offers a digital connected infrastructure and improves efficiency with the right solution for any eligible patient.ZEISS Refractive WorkplaceRefractive Workplace 5 with connectivity to FORUM is the treatment planning software for our refractive lasers.
