Abstract

When relative motion between the target and the camera occurs, the captured images would be blurred. Due to the arbitrariness of the motion, it is of great difficulty to restore the degraded images. In this paper, a new method based on Hartmann-Shack Wavefront Sensor is proposed to deblur the degraded image of the extended target caused by arbitrary motion. Relevant theoretical analysis is given and a corresponding experimental system is built. During the exposure time, image sequences are obtained by the Hartmann-Shack Wavefront Sensor to calculate the displacement vectors, from which the Point Spread Function (PSF) is estimated to restore the blurred image. Experimental results show that the proposed method can efficiently restore the degraded image of the target. So the application of Hartmann-Shack Wavefront Sensor can be extended to detect the motion of target, which means we can deal with wavefront distortion and motion blur using Hartmann-Shack Wavefront Sensor simultaneously.
