ABSTRACT:
A method is disclosed for accurately aligning a shaft in a hole. One application is disclosed for aligning electromagnetic reflectors. An accurately positioned front surface targeted mirror on a predefined reflector axis is used with a reflected laser beam, optical auto-collimation or auto-reflection using an alignment telescope. The mirror is mounted on one end of a shaft which is inserted into a hole of depth l formed through the reflector at the axis, and has formed thereon a reticle at the shaft axis. By aligning the shaft axis with the hole axis in accordance with the invention, extremely accurate alignment of the reflector can be accomplished.
