A new approach to the problem of depth-of-field limitations and distortion in long wavelength imaging systems is proposed. The method exploits the backward propagation imaging algorithm and can be utilised in circumstances where data are recorded in the close near-field region. The fundamental theory of the technique is provided, and images from both simulations and experiment are presented as examples of the process.
