【摘要】 折转光管广泛应用于舰船、车载等光电测量系统中,在方位基准传递过程中,光路在高度上产生折转,入射光与出射光在方位上保证相互平行,从而实现方位基准的保精度传递。对于长度小于1m的折转光管多采用平面镜法或水银盘法检测其光轴平行性,但对于长度大于3m的折转光管,采用上两种检测方法则不能满足其精度指标要求。为此,提出了对于3m长度的折转光管光轴平行性检测的一种新方法,此方法适用于长度大于3m的折转光管光轴平行性的检测。更多还原

【Abstract】 Reflex light-tubes are widely used in optoelectronic measuring systems such as in ships,vehicles and so on.To make the optical path reflex in altitude direction and keep the incident light parallel to the emergent light in azimuth transmission,the reflex light-tubes are needed,which finally ensures precision transmission of the azimuth reference.The flat mirror method and the mercury method are used to test the optical-axis parallelism of reflex lighttubes shorter than 1 m,however when the methods are applied to reflex light-tubes longer than 3 m,the accuracy required cannot be reached.A new test method of optical-axis parallelism for three-meter reflex light-tube is introduced and it is well suited for testing the parallelization of reflex light-tubes more than 3 m.更多还原
