摘要
为了实现大型曲面透明件雾度和透光率的实时测量,设计了一种由LED作为光源、双积分球作为信号测量端的雾度和透光率测试仪。在系统工作原理上完成了透光率和雾度的理论推导,然后进行了光源光谱分布对系统测试结果影响的仿真分析,光学设计,积分球参数设计以及支撑调整机构设计,提高了系统的测试精度和效率。最后,对大型曲面透明件雾度和透光率实时测试仪进行标定和样品测试。测试结果表明:标准雾度片的透过率绝对误差均小于0.4%,雾度绝对误差均小于0.3%,用户提供样品的透过率测量值与理论计算值的偏差亦小于0.4%,满足用户要求。
In order to realize the real-time measurement of haze and light transmittance for large-surface transparent samples,a haze and transmittance tester using LED as the light source and a double integrating sphere as the signal measurement part was designed.First,the theoretical derivation of the light transmittance and haze was completed on the basis of the system scheme.Second,simulation analysis of the light source spectral distribution affecting measurement,optical design,integrating sphere parameter design,and support adjustment mechanism design were completed,increasing the test accuracy and efficiency.Finally,calibration and sample testing of the haze and transmittance realtime tester were conducted.The test results show that the transmittance absolute error of the standard haze sample is less than 0.4%and its haze absolute error is less than 0.3%.Moreover,the transmittance deviation between the measured value and theoretically calculated value of the samples from the subscriber is also less than 0.4%,which confirms the claim of the subscriber.
