Unconventional Astronomical Imaging
Unconventional imaging techniques have been studied to improve the ability to obtain high resolution images of distant objects viewed through a random medium such as the atmosphere. In this paper, the term "conventional imaging" refers to the common case of opening the shutter of a large telescope, collecting photons on film or an electronic detection device, and accepting the result as the final product of the measurement process. Unconventional imaging is distinguished from this definition by three key characteristics: (1) the need to obtain the highest possible resolution in the final image, (2) the use of clever measurement techniques, and (3) the use of post-detection image processing to reconstruct a high quality image from the measurements.
