A method for capturing an image of a moving object in a rotary system, for example, an image of a rotating blade in a gas turbine, uses an endoscope to form an image of a moving object. One-dimensional line images are captured with a line scan image sensor which is oriented to lie orthogonal to the direction of movement of the image of the moving object past the image sensor. Successive line images are combined to form a composite two-dimensional image of the moving object. A second image may be detected using a second line scan image sensor oriented orthogonal with respect to the direction of movement of the image, to the first line scan image sensor.

An inspection system for inspecting an internal component of a machine includes a remote controlled vehicle constructed to fit inside a desired portion of the machine; a controller operative to control an operation of the remote controlled vehicle; a tether coupled to the controller and to the remote controlled vehicle, wherein the tether is operative to transmit control signals from the controller to the remote controlled vehicle; and an imaging device extending from a front portion of the remote controlled vehicle and operative to view the internal component. The imaging device has a flexible articulating tip spaced apart from the front portion of the body.

A laser measurement system for detecting at least one locked blade assembly in a gas turbine. The system includes at least one laser device for emitting a laser beam that impinges on a blade surface of each blade in a row of blade assemblies.
