Abstract
To permit in-flight inspection of an aircraft engine, an imager views the front of the engine, and includes an image intensifier which is gated on and off at the engine speed. Small variations about the engine speed may be used to sweep all the blades into the field of view of an imager which does not view the whole of the front of the engine.
