Reconstruction objects hidden in scattering medium using microlens array

We propose and experimentally demonstrate a new reconstruction method of objects hidden in scattering medium. The object (chicken bone) hidden between two slabs of chicken breast is reconstructed from many speckled images formed by a microlens array (MLA). Each microlens from the array projects a small different speckled image of the hidden object onto a CCD camera. The entire noisy images from the array are digitally processed to yield the hidden object. Following this method, a different algorithm implemented on the same optical system has been developed. This modified algorithm, based on the point-source reference method improve the resolution of the previously method. Experimental results are presented that demonstrate our theory and possible applications of this technique are discussed.
