Imaging technology through scattering materials has been attracting a wide research interest because of its application values in medical imaging and security. Although different technologies have been proposed to conquer the scattering disturbance, it is still a challenge to achieve real-time imaging. A method for fast imaging through scattering medium is presented based on the speckle illumination, Fourier holography and curtain effect. The information of the hidden object can be recovered by a Fourier transform to a single original speckle image. The simple image processing makes the system has the capability of real-time imaging. The non-invasive real-time imaging ability of the proposed method is verified both theoretically and experimentally. The object hidden between scatters is reconstructed successfully and real-time imaging is realized. In addition, a formula for calculating the size of the object is provided. The proposed method can promote the practical application of imaging through turbid media.
