    Abstract: 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.

    Abstract: Disclosed is a first transmitter that transmits a first optical signal towards a target, a plurality of receivers that receive the first optical signal after the first optical signal is reflected by the target and each provides a respective received optical signal, at least one photodetector that receives the received optical signals and provides at least a first electrical signal, and a processor that receives the first electrical signal to compute a position of the target relative to a baseline position based on: a first position of a first receiver of the plurality of receivers, a second position of a second receiver of the plurality of receivers, the first electrical signal. The processor computes a clearance between the target and a component based on a third position of a third receiver, a fourth position of a fourth receiver and a second electrical signal.

    Abstract: A system and method for performing stress measurement on rotating parts is disclosed. The system may include a laser assembly configured to emit a plurality of laser beams having different wavelengths, 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 be configured to output another reflected laser beam onto a second target on the rotatable part. The probe assembly may include a redirector, and a lens assembly mounted proximal to the redirector and configured to converge the laser beams. The redirector may be configured to change the direction of each emitted laser beam.
