Rotating laser measurement system

A scanning mechanism comprising:

• a rotating mechanism;
• a mounting arm rotatably attached to the rotating mechanism;
• a light source connected to the mounting arm, wherein the light source emits a coherent light;
• a mirror connected to the mounting arm, wherein the mirror is positioned to reflect the coherent light;
• a retroreflector attached to the rotating mechanism, wherein the retroflector allows for tracking a relative location of the scanning mechanism;
• and
• a measuring system, wherein the measuring system measures a parameter associated with an object on which the coherent light falls and wherein the measuring system is attached to the mounting arm.

A method for measuring a parameter inside a cavity within an object, the method comprising:

• placing a scanning mechanism into the cavity;
• directing a light from a light source onto a portion of an inside surface of the cavity, wherein the light source is connected to a mounting arm of the scanning mechanism and wherein the mounting arm is rotatably connected to a rotating mechanism of the scanning mechanism;
• and
• measuring an internal parameter of the cavity using a measuring system connected to the mounting arm of the scanning mechanism;
• tracking a relative location of the scanning mechanism using a tracking mechanism, wherein the tracking mechanism determines a distance between the tracking mechanism and the scanning mechanism;
• and
• collecting measurement information from the scanning mechanism and the tracking mechanism using a processing unit that is in communication with the scanning mechanism and the tracking mechanism.

A scanning mechanism comprising:

• a rotating mechanism;
• a mounting arm rotatably attached to the rotating mechanism;
• a first light source connected to the mounting arm, wherein the first light source emits a first coherent light;
• a first mirror connected to the mounting arm, wherein the first mirror is positioned to reflect the first coherent light;
• a first measuring system, wherein the first measuring system measures a first parameter associated with an object on which the first coherent light falls and wherein the first measuring system is attached to the mounting arm;
• a second light source connected to the mounting arm, wherein the second light source emits a second coherent light;
• a second mirror connected to the mounting arm, wherein the second mirror is positioned to reflect the second coherent light;
• and
• a second measuring system, wherein the second measuring system measures a second parameter associated with the object on which the second coherent light falls and wherein the second measuring system is attached to the mounting arm.
