In this paper, we propose a ghost imaging scheme with fast Walsh-Hadamard transform, named GIFWHT. In the scheme, Walsh-Hadamard pattern pairs are used to illuminate an object to generate pairs of detection results, and the corresponding differential detection result is used as the result as that from the conventional bucket detector. By performing the fast Walsh-Hadamard transform on 2(k) (k is a positive integer) differential detection results, the image of the object can be recovered. The experimental and numerical simulation results show that the reconstruction time of GIFWHT is greatly reduced, and the quality of the recovered image is noticeably improved. In addition, GIFWHT is robust against interference from environmental illumination and could save memory. (C) 2016 Chinese Laser Press
