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.
A method for capturing an image of a moving object in a rotary system, comprising using a first endoscope to form an image of a first moving object and to convey the image of the first moving object to a first line scan image sensor, capturing 1-dimensional line images of the first moving object with the first line scan image sensor which is oriented to lie orthogonal to the direction of movement of the image of the first moving object past the first image sensor, and combining successive line images obtained by the first image sensor to form a composite 2-dimensional image of the first moving object, further comprising providing a second endoscope associated with a second line image scan sensor and positioning the second endoscope adjacent a second moving object in the rotary system which is mechanically linked to the first moving object, wherein the second line scan image sensor is oriented orthogonal to the first line scan image sensor, and captures an image of a particular feature of the second moving object.
Apparatus for capturing an image of a moving object in a rotary system, comprising a first endoscope to form an image of the moving object and to convey the image to a first line scan image sensor which is oriented orthogonal to the direction of movement of the image of the object past the first image sensor and which is operable to capture 1-dimensional line images of the moving object, and a processor to combine the line images captured by the first image sensor to form a composite 2-dimensional image of the moving object, further comprising a second endoscope with a second line scan image sensor, the second endoscope arranged to view a second moving object in the rotary system which is mechanically linked to the first moving object in the rotary system, wherein the second line scan image sensor is oriented orthogonal to the first line scan image sensor to capture an image of a particular feature of the second moving object.
