摘要
激光转向器是激光指向仪在井下使用的配套仪器。它可改变巷道中激光指向的任一位置的光束方向,把原光束在水平、垂直方向改变一定角度。激光转向器的使用扩大了激光指向仪的应用范围。一、工作原理激光转向器(图1)
-This instrument is used in combination with a guiding laser, and it is designed on the reflection principles of a plane lens. It consists of an incident chamber, an emergent chamber, a horizontal dial, a microadjuster and a suspension frame. It can change the vertical and horizontal direction of the light beams. The distance can reach 150m. When driving a bend roadway or a roadway with varying gradient it can be used for pointing the direction.
