摘要

We describe a logarithmic phase filter to extend the depth of field of incoherent optical hybrid imaging systems with a rectangular aperture. By introducing this filter at the system's exit pupil and digitally processing the detector's output, we were able to extend the depth of field by an order of magnitude more than the Hopkins defocus criterion.
