Abstract
A phase shifting imaging module in a handheld imager is provided. The phase shifting imaging module includes a first beam splitter configured to split an image radiation beam into first and second image radiation beams. It also includes a first prism configured to align the first and second image radiation beams, and a second beam splitter configured to split the first and second image radiation beams into four image radiation beams. A second prism aligns the four image radiation beams. A phase mask introduces phase retardation between the four image radiation beams, resulting in four phase shifted image radiation beams. A pixilated sensor generates image data based upon each of the four phase shifted image radiation beams.
