In view of the requirements of rotor pressure sensitive paint measurement technology, an image enhancement acquisition method with short exposure for rotor based on a charge-coupled device (CCD) camera was proposed, and a corresponding measurement system was established. Two methods (short-exposure image enhancement acquisition and transient image acquisition) of 9 exposure cases were implemented on the rotor blades of a small-scale fan at 2700 r/min. The experimental results showed that the rotor enhanced acquisition method with short exposure, and the measurement system , can effectively improve the rotor image quality; “no motion blur” image can be achieved when the blur length of the rotating image obtained by using the image enhancement acquisition method with short exposure of the rotor was less than 4 pixels; the brightness of the rotating state image was equivalent to that of the static image when the number of acquisitions equalled to the ratio of static image exposure time to rotating state image exposure time.
