The method of adjustment and examination of Optical axis' parallelism of laser rangefinder

摘要

This paper primarily studies the project of adjustment and examination of optical axis' parallel of a visual device, especially to laser rangefinder's three axes'. One way which uses either big aperture collimation mirror of off-axis paraboloidal mirror or of coaxial paraboloidal mirror is put out and outdoors examination method is also given. Use a tool that can measure the parallelism of optical axis.
