One of the realities in astronomical imaging from the earth is the negative affects introduced by the atmosphere. In order to counteract the effects of the atmosphere, we propose the use of a 3 channel polarimeter and associated deconvolution algorithm. The 3 channel polarimeter features three focal plane arrays simultaneously imaging the same object through polarization analyzers set at angles of 45 and 90 degrees relative to the reference channel. The algorithm is designed to estimate the intensity of the object, its degree of polarization and a term related to its angle of polarization when performing long exposure imaging and the seeing parameter of the atmosphere is known. The results show that a degraded image of 2 point sources can be successfully reconstructed into an image resembling the actual image before the degradation occurred.
