激光准直线在隧道、公路、铁路以及其他相类似的工程中得到广泛的应用,但往往只是局限于利用激光束的瞄准线进行作业。如果设计线为曲线形或是倾斜线,激光束将大大地偏离轴线。因此,通常需将激光器重新定位,也必然会延误工程的进度。为了克服这个问题,Optel 仪器公司研制了一种激光束转向器(如附图所示)。可以 Laser alignment is widely used in tunnels, highways, railways and other similar projects, but it is often confined to working with aiming lines using laser beams. If the design line is curvilinear or slanted, the laser beam will deviate greatly from the axis. Therefore, it is usually necessary to reposition the laser, which will inevitably delay the progress of the project. To overcome this problem, Optel Instruments developed a laser beam redirector (as shown in the attached figure). can
