采用三坐标测量法对磨削加工及模压热成型两种工艺的椭球反光镜进行了面形测量,与标准型线全局比对获得了椭球面形的偏差,结果表明磨削反光镜存在峰谷误差分布,而模压热成型反光镜误差曲线近似于线性分布.采用Tracepro对两种反光镜进行了应用模拟,磨削反光镜的光利用效率是模压热成型反光镜的92%.采用光学成像法观察了反光镜的出射光分布情况,磨削反光镜出射光呈现环状条纹亮暗分布,而模压热成型反光镜出射光呈现云状光强分布.
採用三坐標測量法對磨削加工及模壓熱成型兩種工藝的橢毬反光鏡進行瞭麵形測量,與標準型線全跼比對穫得瞭橢毬麵形的偏差,結果錶明磨削反光鏡存在峰穀誤差分佈,而模壓熱成型反光鏡誤差麯線近似于線性分佈.採用Tracepro對兩種反光鏡進行瞭應用模擬,磨削反光鏡的光利用效率是模壓熱成型反光鏡的92%.採用光學成像法觀察瞭反光鏡的齣射光分佈情況,磨削反光鏡齣射光呈現環狀條紋亮暗分佈,而模壓熱成型反光鏡齣射光呈現雲狀光彊分佈.

Two ellipsoidal surface reflectors, one was made by grinding and the other by molding, were detected using coordinate measuring machine. Contrasting to their profile line, a deviation distribution curve with peaks and valley on the first reflector and a linear deviation distribution on the other one are acquired. TracePro was used to simulate luminance of their reflecting spot and a reflecting effect ratio of 92%comparing between the two reflectors is obtained. Optical imaging method was used to inspect the reflected light spot and the result shows that bright and dim rings appear alternately in the reflected spot of the grinding reflector, and the other one gets a cloud-like reflected light spot.
