Paper Abstract
Lock-in imaging enables high contrast imaging in adverse conditions by exploiting a modulated light source and
homodyne detection. We report results on a patent pending lock-in imaging system fabricated from commercial-off-theshelf
parts utilizing standard cameras and a spatial light modulator. By leveraging the capabilities of standard parts we
are able to present a low cost, high resolution, high sensitivity camera with applications in search and rescue, friend or
foe identification (IFF), and covert surveillance. Different operating modes allow the same instrument to be utilized for
dual band multispectral imaging or high dynamic range imaging, increasing the flexibility in different operational
settings.
