A process for aligning a laser in a gear inspection system is disclosed. The method comprises fixing a gear for inspection within a gear inspection system and emitting a first signal from a laser to a point of interest of the gear. A reflection of the first signal is received as the first signal reflects off the point of interest of the gear. Based on the reflection of the first signal, an orientation of the laser is adjusted. Subsequently, a second signal is emitted from the laser to the point of interest of the gear, and a reflection of the second signal is received as the second signal reflects off the point of interest of the gear. Values corresponding to the orientation of the laser are stored based on the reflection of the second signal.

There is provided a profile measuring apparatus, including: an irradiation section configured to irradiate a measurement light to a measurement area of the object; an imaging section configured to obtain an image of the measurement area; a table configured to place the object thereon; a coordinate calculation section configured to calculate a position of the measurement area based on an image detected by a detection section; and a positioning mechanism configured to drive and control a relative position of the imaging section and the table. The positioning mechanism calculates a relative position of the imaging section to the table, based on an information with respect to an edge line direction of a convex portion or an extending direction of a concave portion in the measurement area of the object having a repetitive concave-convex shape, to move at least one of the table and the imaging section.
