Description

消除湍流效应的开放式长光程多次反射池系统
技术领域
本发明涉及光学仪器领域,尤其是反射池,具体为一种消除湍流效应的开放式长光程多次反射池系统。
背景技术
开放式多次反射池中,大气湍流效应会对光路产生扰动。具体情况为:1、大气湍流效应增加时,多次反射池内光路受湍流效应扰动的影响,使光路发生偏移;2、多次反射池主镜与次镜之间距离增大后,稍有大气湍流效应的影响,就会使多次反射池内的光路发生偏移。
发明内容
本发明的目的是提供一种消除湍流效应的开放式长光程多次反射池系统,以解决大气湍流效应对反射池光路的干扰。
为了达到上述目的,本发明所采用的技术方案为:
消除湍流效应的开放式长光程多次反射池系统,包括由相对设置的主镜和次镜构成的反射池,其特征在于:所述反射池外设置有出光口正对所述主镜一端的激光器,所述激光器与主镜之间的光路上设置有半反半透透镜,反射池一侧还设置有接收端对准所述半反半透透镜的光电探测器,位于次镜反射光路上的主镜另一端的外镜面上安装有直角反射镜,所述直角反射镜的斜面紧贴在主镜上。
激光器的出射光经过半反半透透镜进入由主镜和次镜组成的长光程多次反射池系统,光束在长光程多次反射池内经多次反射到达直角反射镜;在直角反射镜内经过2至3次反射后,沿原光路在多次反射池内经多次反射返回至半反半透透镜;光束经半反半透透镜反射至探测器。通过直角反射镜将反射池中反射光再次按原光路反射回去,有效地消除了由于大气湍流效应对反射池中光路的干扰。
本发明实现了对长光程多次反射池内湍流效应的消除,消除了长光程多次反射池内的湍流效应影响对于减少光路上湍流效应对光束的扰动、提高了多次反射池出射光束稳定性、增加了长光程多次反射池的总光程。
附图说明
图1为本发明光路示意图。
具体实施方式
如图1所示。消除湍流效应的开放式长光程多次反射池系统,包括由相对设置的主镜3和次镜4构成的反射池,反射池外设置有出光口正对主镜3一端的激光器1,激光器1与主镜3之间的光路上设置有半反半透透镜2,反射池一侧还设置有接收端对准半反半透透镜2的光电探测器6,位于次镜4反射光路上的主镜3另一端的外镜面上安装有直角反射镜5,直角反射镜5的斜面紧贴在主镜3上。
激光器1的出射光经过半反半透透镜2进入由主镜3和次镜4构成的长光程的多次反射池,光束在反射池内经多次反射到达角反射镜5;在角反射镜5内经过2至3次反射后,沿原光路在多次反射池内经多次反射返回至半反半透透镜2;光束经半反半透透镜反射至探测器6。
