NOISE 2 imaging system: seeing through scattering tissue with a reference point.
Journal Title: Optics Letters - Year 2004, Vol 29, Issue 9
Abstract
We propose a fly-eye-like imaging system for seeing objects embedded inscattering media. Objects are recovered from many speckled images observed by a digital camera througha microlens array. Each microlens in the array generates a speckle image of the object buried betweentwo layers of chicken breast tissue. In the computer each image is Fourier transformed jointly with animage of the speckled pointlike source captured under the same conditions. A set of the squared magnitudesof the Fourier-transformed pictures is accumulated to form a single average picture. This final pictureis again Fourier transformed, resulting in the reconstruction of the hidden object.

Noninvasive optical imaging by speckle ensemble.
We propose a new method imaging through scattering media. An object hiddenbetween two biological tissues (chicken breast) is reconstructed from any speckled images obtained fromthe output of a multichannel optical imagin...
