Current shared aperture diffractive optical elements (SHADOE) have intrinsic residual wavefront errors on the order of 20 waves which limits the angular resolution of the LIDAR application to a range between 150 and 400 micro-radians. It is possible to reduce these aberrations by constructing a… More
Current shared aperture diffractive optical elements (ShADOE) have intrinsic residual wavefront errors on the order of 50 waves which limits the angular resolution of the LIDAR application to about 300 micro-radians. We have reduced these aberrations by constructing a secondary holographic… More
This Small Business Innovation Research (SBIR) Phase I project seeks to demonstrate that 840 nm spectral domain optical coherence tomography (OCT) can provide images equal to or better than those currently available from swept source OCT, with the added advantages of higher imaging speeds and lower… More
