EVT Eye Vision Technology GmbH产品
EVT的Eyevision软件现在还支持带蓝色激光的3D激光三角测量传感器。因此，3D扫描仪的新耳塞更适合扫描金属或金属表面。今天的非接触式3D扫描仪包括两个激光类型之一：蓝色激光或红色激光。大多数3D扫描仪，包括来自EVT的Eyescan 3D扫描仪，用户红色激光技术。然而，3D蓝色的新eyescan利用光学优越的蓝色激光技术。蓝紫色激光有一些明显的优点。一个优点是更好的扫描结果。蓝色激光器在其侧面有物理定律，因为它具有比红色激光更短的波长。结果，蓝色激光器提供更高的扫描结果，分辨率更高，高达数据噪声减少50％。由于较短的波长，激光散斑图案较小，从而产生更清晰的深度图像。 The blue laser has more effects when scanning metal, because a blue laser is narrower and finer than a red laser line. Thanks to 20.000 profiles per second and the new blue laser, even complex component parts and surfaces can be captured with high accuracy. The extremely fast scans are possible due to the short exposure time. Additionally the EyeScan AT 3D Blue has a high quality Schleimpflug optic, and therefore even with a big lens and short exposure time a sharp image is possible. And also the lens is of such quality, that there is no lens correction necessary. Also what makes the EyeScan AT 3D Blue fast is the laser class 3 and the preprocessing of data with a FPGA inside the scanner. And the high dynamic range with 3time exposure, makes it possible that dark and bright objects can be inspected in one scan, without a decrease in speed.
