We report a new optical arrangement that creates high-efficiency, high-quality fresnel incoherent correlation holography (finch) holograms using polarization sensitive transmission liquid crystal gradient index (tlcgrin) diffractive lenses. in contrast, current universal practice in the field employs a reflective spatial light modulator (slm) to separate sample and reference beams. polarization sensitive tlcgrin lenses enable a straight optical path, have 90% transmission efficiency, are not pixilated, and are free of many limitations of reflective slm devices. for each sample point, two spherical beams created by a glass lens in combination with a polarization sensitive tlcgrin lens interfere and create a hologram and resultant super resolution image.
