N2 - We propose and experimentally demonstrate a new method of seeing objects hidden in scattering medium from multiple speckle images. The objects hidden between two biological tissues (chicken breast) are reconstructed from many speckled images formed by a microlens array. Each microlens from the array projects a small different speckle image of the hidden object onto a CCD camera. The entire noisy images from the array are digitally processed to obtain the desired image of the hidden objects. Following the first proposed method, a different algorithm implemented on the same optical system has been developed. This modified algorithm, based on the point-source reference method improves the resolution of the previous method. Laboratory experiments with two kinds of objects are presented.
