TRAVERSING TIME OF ARRIVAL PROBE

摘要

A system and method for performing stress measurement on rotating parts is disclosed. The system may include a laser assembly configured to emit a laser beam, and a probe assembly mounted proximal to a rotatable part in a device. The probe assembly may be configured to output a reflected laser beam onto a first target on the rotatable part. The probe assembly may further be configured to move the reflected laser beam from the first target to a second target on the rotatable part. The probe assembly may include a redirector moveable from a first position to a second position, and a lens mounted proximal to the redirector and configured to focus the laser beam. The redirector may be configured to change the laser beam direction from a first direction to a second direction when moved from the first position to the second position.

1. A traversing time of arrival probe system for stress measurement of rotatable parts, the system comprising:
a laser assembly configured to emit a laser beam; and a probe assembly disposed proximal to a rotatable part in an engine, the probe assembly configured to output a reflected laser beam onto a first target on the rotatable part, the probe assembly further configured to move the reflected laser beam from the first target to a second target on the rotatable part, the probe assembly including:
a redirector moveable from a first position to a second position, the redirector configured to change the laser beam direction from a first direction to a second direction when moved from the first position to the second position; anda lens mounted proximal to the redirector and configured to focus the laser beam.
