Abstract: A flow angle sensor includes a sensing element, a background component connected to and movable with the sensing element, the background component having a marker, a lens (32) adjacent the disk, an image sensor (34) axially aligned with the lens, a light source (38) positioned to illuminate the disk, and an image processing system (36) connected to the image sensor (34). The image processing system (36) provides an angle of attack output based on a location of the marker sensed by the image sensor.
