Summary on Grant Application Form |

The optical phased array for imaging in heavily scattering media described in this proposal has the advantage of being able to scan without physically moving the sources and also to make accurate measurements of relative amplitude, enabling reconstruction to be more robust. Currently only the basic principle has been demonstrated and there is much scope for improving system performance. The overall aim of this proposal is to improve the performance of phased arrays by detailed system analysis, novel modulation techniques and a reconstruction algorithm specific to phased arrays. A detailed analysis of the system parameters and scanning mechanisms will be performed to determine the optimum configuration. Interferometric modulation will be used to provide higher modulation frequencies at greater modulation depths, enabling more localisation at a better SNR. Furthermore, generating the phased array sources from a single source eliminates noise from uncorrelated amplitude fluctuations. This has the additional advantage of accurately measuring the relative amplitude for robust reconstruction. A reconstruction algorithm specific to phased arrays will enable the scanning mechanisms and multiple object reconstruction to be properly evaluated. The knowledge obtained in this project forms part of a long term research plan to construct novel instrumentation closely linked to medical collaborators.
