摘　　要：隧道断面激光放样仪基于嵌入式系统 ,用平移物镜法实现了在开挖断面上的激光点扫描 ,用单透镜准直法对发散角较大的半导体激光器实现了准直 ,满足了放样仪器体积小、便于携带、自动放样的要求。讨论该仪器硬件。The principles of laser lofting instrument for railroad tunnel are introduced based on embedded system.Among this technique,we use a simple,economical and practical collimation method single lens to collimate semiconductor laser beam,and use moving objective scanning method to make laser point scan on the lofting plane.It can be make the lofting instrument lighter and easy to be carried and is automatic.The crucial technology that this instrument hardware and software realize are described.
