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.
