Claim One:
1. A method of extracting data from an identifiable monochromatic pattern, said method comprising: using a optical assembly having a mask with a at least concentric ring for separating a polychromatic optical signal, received from an object having identifiable monochromatic pattern, into a plurality of wavelength components; using an image sensor having a plurality of color channels for separately capturing each of said plurality of wavelength components in another color channel of said plurality of color channels; reconstructing a plurality of images each from a different color channel of said plurality of color channels that includes a different wavelength component of said plurality of wavelength components; detecting said identifiable monochromatic pattern in at least one of said plurality of images; and extracting data associated with or encoded by said detected identifiable monochromatic pattern; wherein each of said plurality of images has a different depth of field; wherein said mask and said image sensor are aligned along a common axis.
