摘要

摘要: 通过3D扫描的方法，对椭球反光镜的面形进行了检测，并与标准椭球面形进行最佳拟合对比，以E210反光镜为例。结果表明：3D扫描能够完成椭球反光镜的检测，E210反光镜在底孔部位存在加工过量，在端口部位存在近似十字形对称的加工不足的现象，加工误差范围为-0.06 mm ~+0.08 mm，符合轮廓度误差0.1 mm的要求。3D扫描点云能够进行逆向反求并建立实际反射面模型，进一步模拟反光镜的反射光斑形状、大小等参数，模拟结果与检测结果一致。

Abstract: By using 3D scanning detection method, we measured the surface of ellipsoidal reflector and performed the best fitting contrast with the standard ellipsoidal suface-taking E210 reflector as an example. The result shows that the 3D scan detection method is capable of ellipsoidal reflector inspection, and the E210 ellipsoidal reflector is processed excessively on the bottom and insufficiently on the top in an approximate shape like cross. The processing error is -0.06 mm~+0.08 mm, which meets the limited profile error range of -0.1 mm~+0.1 mm. We carried out the reverse calculation according to the scanned point cloud data and established an actual reflection surface model, moreover, further simulation of reflector parameters, such as reflecting spot shape and size, was accomplished. The simulation results correspond well to the test result.
