Snapshot multispectral imager for medical applications

A method of using a camera comprising the steps of:

• passing an image through a first filter tray and an objective lens, wherein the first filter tray comprises a plurality of first elements, each first element passes a unique spectral frequency band of light preselected for a first diagnostic medical imaging application;
• selecting the unique spectral frequency band that each first element passes based on the following center wavelength values in nanometers (nm), plus or minus 1 percent:
• 425.3, 469.4, 517.2, 535.6, 540.1, 560.2, 561.4, 574.9, 612.0, 649.2, 684.6, 800.3, 852.0 and 900.0;
• focusing, via the objective lens, the image onto a micro-lens array (MLA) comprising a plurality of micro lenses;
• re-imaging the image, via each one of the plurality of micro lenses, onto each one of a plurality of sensors within a focal plane array (FPA);
• filtering each re-image associated with each one of the plurality of micro lenses into a number N of spectral bands, where N is equal to or greater than two;
• generating an image for each spectral band;
• and
• processing the generated images for each spectral band to determine a parameter.
