A high-quality, large numerical aperture Fresnel zone device is being developed to enhance the performance of a Fabry-Perot interferometer (FPI) system. As predicted by the theory, the contributions from the successive interference fringes transmitted by this multiple Fresnel aperture increase the throughput of the FPI system many fold. This versatile optical element can also function as a lens, an aperture and a filter resulting in a very compact system. For a given FPI resolution, a dramatic increase in the throughput and significant reduction in the instrument size attained by this experimental approach offers broad possibilities for major scientific advances for faint radiation measurements in several areas including astronomy, remote sensing of the atmosphere, X-ray microscopy, plasma research, and neutron imaging.
